037c9ea0a4 arch/arm: Rename all up_*.h files to arm_*.h
Summary

The naming standard at https://cwiki.apache.org/confluence/display/NUTTX/Naming+FAQ requires that all MCU-private files begin with the name of the architecture, not up_.

This PR addresses only these name changes for the up_*.h files.  There are only three, but almost 1680 files that include them:

    up_arch.h
    up_internal.h
    up_vfork.h

The only change to the files is from including up_arch.h to arm_arch.h (for example).

The entire job required to be compatible with that Naming Convention will also require changing the naming of the up_() functions that are used only within arch/arm and board/arm.

Impact

There should be not impact of this change (other that one step toward more consistent naming).

Testing

67ec3d7926 Remove CONFIG_CAN_PASS_STRUCT
This commit resolves issue :

Remove CONFIG_CAN_PASS_STRUCTS 

The configuration option CONFIG_CAN_PASS_STRUCTS was added many years ago to support an old version of the SDCC compiler. That compiler is currently used only with the Z80 and Z180 targets. The limitation of that old compiler was that it could not pass structures or unions as either inputs or outputs. For example:

    #ifdef CONFIG_CAN_PASS_STRUCTS
    struct mallinfo mallinfo(void);
    #else
    int      mallinfo(FAR struct mallinfo *info);
    #endif

And even leads to violation of a few POSIX interfaces like:

    #ifdef CONFIG_CAN_PASS_STRUCTS
    int  sigqueue(int pid, int signo, union sigval value);
    #else
    int  sigqueue(int pid, int signo, FAR void *sival_ptr);
    #endif

This breaks the 1st INVIOLABLES rule:

Strict POSIX compliance
-----------------------

  o Strict conformance to the portable standard OS interface as defined at
    OpenGroup.org.
  o A deeply embedded system requires some special support.  Special
    support must be minimized.
  o The portable interface must never be compromised only for the sake of
    expediency.
  o Expediency or even improved performance are not justifications for
   violation of the strict POSIX interface

Also, it appears that the current SDCC compilers have resolve this issue and so, perhaps, this is no longer a problem: 

NOTE:  This commit cannot pass the PR checks because it depends on matching changes to the apps/ directory.

5c80b94820 Replace #include <semaphore.h> to #include <nuttx/semaphore.h>
Since the kernel side should call nxsem_xxx instead and remove the unused inclusion

6a3c2aded6 Fix wait loop and void cast ()
* Simplify EINTR/ECANCEL error handling

1. Add semaphore uninterruptible wait function
2 .Replace semaphore wait loop with a single uninterruptible wait
3. Replace all sem_xxx to nxsem_xxx

* Unify the void cast usage

1. Remove void cast for function because many place ignore the returned value witout cast
2. Replace void cast for variable with UNUSED macro

cxd56xx: various fixes

* arch: arm: cxd56xx: Support to set any i2c frequency

    This commit supports to be able to set the i2c frequency other than just
    100 or 400 Hz.

* arch: arm: cxd56xx: Enable SD clock during access to SD card

    - Improve GNSS low sensitivity with SD card inserted
    - Reduce power consumption by stopping SD clock

* arch: arm: cxd56xx: Do PANIC() when cpu rx fifo is overflow

    If CPU Rx FIFO is overflow, it's fatal error for system. In such a case,
    this commit changes to allow the user to notice by calling PANIC() for
    debuggability enhancement.

* arch: arm: cxd56xx: Fix compile error in sdhci debug code

* arch: arm: cxd56xx: Remove assertion in cpu tx queue

    When CPU Tx queue is overflow, it returns -EAGAIN instead of assertion
    to be able to retry.

* arch: arm: cxd56xx: Add configurations for cpu fifo elements

* arch: arm: cxd56xx: Fix LPADC configuration

    LPADC options defined in the same symbol name, so kconfig tool
    couldn't process them correctly.

* arch: arm: cxd56xx: Update loader and gnssfw ver.17660

* arch: arm: cxd56xx: Fix hang-up when error interrupt occurs

    Fix a problem that error interrupts are not cleared.

* boards: cxd56xx: Treat the initial value of LNA power as off

    LNA is always turned power on when GNSS is started. So it is desirable
    that the initial value of the LNA power is off by default.

* boards: cxd56xx: Remove initial setting of PIN_AP_CLK

    PIN_AP_CLK is used as a port selector of SDIO expander on the extension
    board, and is set output low in initalizing. Therefore, this pin cannot
    be used for other board. To avoid this restriction, remove this initial
    operation because this pin is pulled down by default on the extension
    board.
