Add a function to easily enable event handling on fabric and mss gpios. This
is similar to what exists e.g. for stm32 arm chips.
Also fix some small bugs in mpfs_configgpio related to IRQ bits configuration

This patch fixes the following issues:
1. MPFS_EMMCSD_HRS06_EMM bitmask had to be 0x7, not 0x03
2. putreg32() caused outright memory corruption as the
arguments were in wrong order

The old implementation needed a contiguous memory block for user
ROM/RAM. This is because there was only 1 L3 page table which can only
map a contiguous memory area.
Also, remove the PMP configuration which just complicates things,
rely on the MMU mappings instead.
Update PLL configuration parameters to match the values provided
by the vendor.
Also remove extra call to mpfs_pll_config() as it's already called
at mpfs_clockconfig().

Summary:
- I noticed that sometimes uart shows nothing on the maix-bit board.
- This commit adds a workaround to avoid such the issue
Impact:
- k210 only
Testing:
- Tested with maix-bit

This provides USB composite (CDC/ACM and Mass Storage) support
for mpfs board. In addition, a number of USB fixes are included:
- Support for Setup Out packets
- Proper support for larger than packet size writes
- Finishing setup packets properly

Output "X" with showprogress and make a system reset.
Silently ignoring failed training is dangerous and will cause random behaviour if DDR is used

Linux kernel uses M-mode trap for handling Inter-Hart Communication (IHC).
This patch provides all the required functionalities for this purpose.
Previously, HSS bootloader was required. Now, NuttX is run as the
bootloader providing OpenSBI vendor extensions instead. This setup has
been tested on the following configuration:
- Hart 0 has NuttX in bootloader mode with OpenSBI
- Hart 1 unused
- Hart 2 has NuttX configured at 0xa2000000
- Hart 3 has U-boot / Linux kernel (at 0x80200000)
- Hart 4 has U-boot / Linux kernel (at 0x80200000)
Upon startup, NuttX on hart 0 will initialize SD-card driver, loads
the hart 2 NuttX from the SD-card and loads the U-boot to 0x80200000.
Also the nuttx.sbi -binary is loaded from SD-card into address 0x80000000,
which is also marked as reserved area in the Linux kernel device tree (for
the chuck 0x80000000 - 0x80200000).
Hart 2 NuttX waits until Linux kernel (IHC master) is started. After the
initial handshake, RPMsg / virtIO bus along with the IHC may be used for
proper AMP mode.

The FPU register saving upon vfork entry was missing.
Also added macro that tells the actual size of an FPU reg, instead
of just having a coefficient for qfpu/no-qfpu.
- Remove most of the ifeq-conditions and replace them with variables.
- Move the -I flag for 3rd party headers to opensbi/Make.defs
This clean-up / generalization makes it much simpler to add a new SBI
implementation, without the need to add a bunch of ifeq / elif conditions
to the makefile.
Let the user pick what runs on the harts. For example, the
default configuration now supports NuttX on hart2 and Linux
kernel on harts 3 and 4. Also fix a few issues in the code.
