[PATCH] riscv: merge two if-blocks for KBUILD_IMAGE

[PATCH] riscv: merge two if-blocks for KBUILD_IMAGE

[Masahiro Yamada]

In arch/riscv/Makefile, KBUILD_IMAGE is assigned in two separate
if-blocks.

When CONFIG_XIP_KERNEL is disabled, the decision made by the first
if-block is overwritten by the second one, which is redundant and
unreadable.

Merge the two if-blocks.
