npcx: Add CHIP_VARIANT variant for different versions of npcx ec.
In order to support 256 KB ram version of npcx ec, we add CHIP_VARIANT
variant to distinguish which verson ec is.
In config_chip.h, we use CHIP_VARIANT to specify the size and start address
of program memory. Ecst tool also needs a chip parameter to make sure
the address range checking of entry pointer won't fail.
Modified sources:
1. config_chip.h: Use CHIP_VARIANT to specify the different hardware spec
of npcx ec.
2. config_flash_layout.h: Replace constant value with
CONFIG_PROGRAM_MEMORY_SIZE for CONFIG_RO_SIZE.
3. build.mk: Add -chip parameter for ecst tool to check entry address.
4. npcx_evb\build.mk: Add CHIP_VARIANT definition (npcx5m5g).
5. npcx_evb_arm\build.mk: Add CHIP_VARIANT definition (npcx5m5g).
6. wheatley\build.mk: Add CHIP_VARIANT definition (npcx5m5g).
