Prior to this patch TCR_EL1 was incorrectly initialized with bit 32 set
to 0. On Cortex-A57 this bit is RES1 so this bit should always be set to
1, this patch fixes that.
This is related to errata 822227
"Using unsupported 16K translation granules might cause Cortex-A57 to
incorrectly trigger a domain fault"
