arm64: kernel: remove SHF_WRITE|SHF_EXECINSTR from .idmap.text
commit d54170812ef1 ("arm64: fix .idmap.text assertion for large kernels")
modified some of the section assembler directives that declare
.idmap.text to be SHF_ALLOC instead of
SHF_ALLOC|SHF_WRITE|SHF_EXECINSTR.
This patch fixes up the remaining stragglers that were left behind. Add
Fixes tag so that this doesn't precede related change in stable.
