soc: andestech: linker.ld: fix incorrect padding of rom_mpu_padding

jimmyzhe · carlescufi · commit da99144891e4 · 2024-10-23T16:53:13.000+02:00
The rom_mpu_padding section is incorrect NAPOT padding for the address of
__rodata_region_end when ROM_BASE is not 0x0, because __rom_region_start
is set to the offset of rom_start section.

Fixed this by use "__rom_region_start = ABSOLUTE(.);" to keep both
__rodata_region_end and __rom_region_start are absolute address.
