[PATCH] riscv: Fix alignment of RELA sections in the linker scripts

[Bin Meng]

In current linker script both .efi_runtime_rel and .rela.dyn sections
are of RELA type whose entry size is either 12 (RV32) or 24 (RV64).
These two are arranged as an continuous region on purpose so that the
prelink-riscv executable can fix up the PIE addresses in one loop.

However there is an 'ALIGN(8)' between these 2 sections which might
cause a gap to be inserted between thesse 2 sections to satify the
alignment requirement on RV32. This would break the assumption of
the prelink process and generate an unbootable image.

Fixes: 9a6569a043d3 ("riscv: Update alignment for some sections in linker 
scripts")

This fix should go into the v2023.07 release.
