This patch adds support for the Amlogic AXG SoC, which is very close from
the Amlogic GXL SoCs with :
- Same 4xCortex-A53 CPUs but clocked at 1.2GHZ max
- DDR Interface limited to DDR4 16bit
- The whole physical register address space has been moved to 0xfxxxxxxx
- The pinctrl setup has changed
- The clock tree is different enough to use a different driver

The original chosen addresses conflict with the BL2 initialisation.
So far there was no issue with them but if we preload binaries in
RAM (ROMUSB boot) before running the BL2 they get corrupted by the
execution of BL2 init.
If we load them around 0x08000000, there is no such issue.

Rework the board SYS_BOARD, SYS_VENDOR and SYS_CONFIG_NAME setup by moving
the board Kconfig into the mach-meson Kconfig to make it easier to add
new boards for a SoC architecture and add a custom config header or custom
board handler for a platform.
This drops the board CONFIGs and the duplicate boards configs headers in
favor of a single meson64.h config header.

Add in the ability to modify the distro boot filename. Whilst not
immediately useful in normal usage, it allows an alternative
configuration to be provided when other u-boot functionality is used, such
as bootcount limit, to fallback to an alternative boot configuration. In
this case we can follow the same boot path as for normal boot, just
using an alternatively named configuration file.
For example, by providing the following `altbootcmd` when bootcount is in
use:
altbootcmd=setenv boot_extlinx_conf extlinux-rollback.conf; \

It would be convenient if one could use the regmap API in conjunction
with register maps defined as structs (i.e. structs that directly mirror
the memory layout of the registers in question). A similar approach was
planned with the regmap_write32/regmap_read32 macros, but was never
used.
Hence, implement regmap_set/regmap_range_set and
regmap_get/regmap_range_get macros, which, given a register map, a
struct describing the layout of the register map, and a member name
automatically produce regmap_read/regmap_write calls that access the
specified member in the register map.

To rectify this, implement the regmap_raw_read and regmap_raw_write

read or write operation on a regmap.
