Make use of XCHG/BSWAP on x86, REV16 and REV on ARMv6-m and above,
and whatever other optimized instructions on other platforms.
Defines extra CONFIG variables, and removes the unused functions for
endian-swapping. Fixes some oversights in using the macros.
Starting the rptun with the autostart flag set will cause significant
delays at the boot, as it will wait for the master to be up. U-boot/linux
combination may take more than 10 seconds to boot to the point where the
rpmsg bus is initialized.
For now, the user needs to initialize the rptun separately, for example,
by issuing the following command:
rptun start /dev/rptun/mpfs-ihc
This command will also block if started before the rpmsg bus master is up.

Move the linker defined symbols to a separate file, so they can be
accessed without pulling in everything from riscv_internal.h and
whatever it includes (e.g. syscall.h drags in a lot).
SAMA5D2 and SAMA5D4 does not support external reset.
Some SAMA5 board's Kconfig contain item SAMA5_SYSTEMRESET, but it is better in arch/arm/src/Kconfig.
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

When using HSE to clock RTC NuttX internal time is gaining 5.5 second per
minute. Problem was NuttX using 7182 for one of the RTC division factors,
it should have been 7812. The incorrect factors used are 7182 and 0xff.
These are used in 3-4 places within Nuttx and other places as 7812 and 0xff.
However, the STMicro app note AN4759 suggests using 7999 and 124, which is
what I've used.
Explanation: These 2 factors are used to divide the HSE clock (which at this
point is 1 MHz) to 1 Hz for the RTC hardware.
To test the 2 factors, add 1 to both numbers and multiply them together.
The result needs to be as close as possible to 1 MHz.
The suggested values of 7999 and 124 => 8000*125 = 1,000,000, the prime
factors. So, the best fix for Nuttx would be these values.

In order to support multiple LCD instances per board, add a pointer from
lcd_planeinfo_s to the lcd_dev_s which it belongs to. Also enhance the
putrun, getrun, putarea and getarea methods to pass through the
lcd_dev_s pointer to the respective device driver.
Port all LCD device drivers to this lcd_planeinfo_s extension.
Enhance SSD1306 driver to support multiple LCDs.
