[PATCH] powerpc/mm: Fixup wrong LPCR_VRMASD value

In commit a4b349540a26af ("powerpc/mm: Cleanup LPCR defines") we updated
LPCR_VRMASD wrongly as below.

-#define   LPCR_VRMASD  (0x1ful << (63-16))
+#define   LPCR_VRMASD_SH       47
+#define   LPCR_VRMASD          (ASM_CONST(1) << LPCR_VRMASD_SH)

We initialize the VRMA bits in LPCR to 0x00 in kvm. Hence using a different
mask value as above while updating lpcr should not have any impact.

This patch updates it to the correct value
Fixes: a4b349540a26af ("powerpc/mm: Cleanup LPCR defines") we updated
