The stm32_gpiosetevent calls stm32_configgpio. So
the pin is infact restored to the SDMMC/SDIO D0.
The seconday init, dropped interrupts in a debug
build with HW stack checking on after the GPIO glich
fixes and that was how it was detected.
This prevents gliches on changing to an output mode.
If not the ALT mux can be selecting a IP block that
is drving the line to say 0. Then the output is connected
to that source, then swithced to the correct source.

produced a 430 nS glich on a F4 @168 Mhz. It was a enough
to corrupt an I2C device with a bus monitor.
During the lcd1602 tests on our internal CI we noticed that the
lcd1602 was failing because there is not a I2C display in the
emulated board on QEMU. It is better to remove the "return ret"
from the bringup because the user will see the error anyway.

drivers/syslog: Call up_puts in syslog_default_write instad up_putc
since some drivers(e.g. semihosting) have more fast implementation.

The resulting time complexities are as follows:
* devif_callback_alloc() time complexity is O(1) (i.e. O(n) to fill the whole list).
* devif_callback_free() time complexity is O(1) (i.e. O(n) to empty the whole list).
* devif_conn_event() time complexity is O(n).
The nxstyle check tool can't recongnize the style error that --, -> or ++ is not next to the operand. For example, "idx ++;", "p ->member" or "(-- idx)", which is in incorrect style, is not recongnized. This patch add detection for these cases.

In case of enabled packet forwarding mode, packets were forwarded in a reverse order
because of LIFO behavior of the connection event list.
The issue exposed only during high network traffic. Thus the event list started to grow
that resulted in changing the order of packets inside of groups of several packets
like the following: 3, 2, 1, 6, 5, 4, 8, 7 etc.
Remarks concerning the connection event list implementation:
* Now the queue (list) is FIFO as it should be.
* The list is singly linked.
* The list has a head pointer (inside of outer net_driver_s structure),
and a tail pointer is added into outer net_driver_s structure.
* The list item is devif_callback_s structure.
It still has two pointers to two different list chains (*nxtconn and *nxtdev).
* As before the first argument (*dev) of the list functions can be NULL,
while the other argument (*list) is effective (not NULL).
* An extra (*tail) argument is added to devif_callback_alloc()
and devif_conn_callback_free() functions.
* devif_callback_alloc() time complexity is O(1) (i.e. O(n) to fill the whole list).
* devif_callback_free() time complexity is O(n) (i.e. O(n^2) to empty the whole list).
* devif_conn_event() time complexity is O(n).
This adds the emmcsd driver for the Polarfire Icicle kit.
The driver has been tested with several SD-cards, such as:
- Kingston 32 GB SDS2 Canvas Select Plus
- Kingston MicroSD Canvas Select Plus
- Sandisk Extreme PRO 32 GB
- Transcend 8 GB MicroSD
The internal eMMC hasn't been tested comprehensively.

Because of this, it will take some time to detangle the licensing under net/. Many new features, original features were added to the NuttX network. Clearly, any references to Adam Dunkels in the files that implement these new features that have no counterpart in uIP 1.0 are errors.
This PR removes the references and converts the license headers to Apache 2.0 where possible. The affected files include only (1) the implementation of IPv6 (including neighbor support under ICMPv6) and (2) Raw sockets. Neither of these features are present in uIP 1.0 and the licenses can be freely updated.
Make sending commands independent of processor endianness. The data can
be handled by application side, such as LVGL has SWAP16 option.

Also I have set the parameter to 8 instead of 4 by default
because there were many "alloc failed" messages in debug log
even during initialization / automatic IP address assignment
via DHCP negotiation.
Summary:
- This commit replaces the critical section with spinlock in cxd56_serial.c
Impact:
- None
Testing:
- Tested with spresense:rndis_smp, spresense:rndis
and spresense:rndis_wifi
