ARM: 7808/1: KVM: mm: Get rid of L_PTE_USER ref from PAGE_S2_DEVICE
THe L_PTE_USER actually has nothing to do with stage 2 mappings and the
L_PTE_S2_RDWR value sets the readable bit, which was what L_PTE_USER
was used for before proper handling of stage 2 memory defines.
Changelog:
[v3]: Drop call to kvm_set_s2pte_writable in mmu.c
[v2]: Change default mappings to be r/w instead of r/o, as per Marc
Zyngier's suggestion.
