Kernel 6.6 checks for orphan sections and prints a warning about them,
which in turn will make CI fails as we have Werror enabled there.
Issue is that cache-v7-min.S produces .init.text section which is an
orphan section since it is not being handled by the vmlinux.lds.S linker
script.
So, lets put the generated .init.text section under .text.
