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.

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().

- change (1 << n) to (1 << (n)) in macro definition
- change 1 << X to (1 << X) in code
- fix alignment
v2 -> v3:
Suggested by: Petro Karashchenko
- I was supposed to change (1 << pin) to 1 << pin, not the other way around:)
Summary:
