Christophe Leroy 7636d4275a powerpc/8xx: Fix initial memory mapping

[ Upstream commit f9f2bff64c2f0dbee57be3d8c2741357ad3d05e6 ]

Commit cf209951fa ("powerpc/8xx: Map linear memory with huge pages")
introduced an initial mapping of kernel TEXT using PAGE_KERNEL_TEXT,
but the pages that contain kernel TEXT may also contain kernel RODATA,
and depending on selected debug options PAGE_KERNEL_TEXT may be either
RWX or ROX. RODATA must be writable during init because it also
contains ro_after_init data.

So use PAGE_KERNEL_X instead to be sure it is RWX.
