[meta-xilinx] [PATCH 4/4] arm-trusted-firmware: Fix a false positive out of bounds

[Alistair Francis]

This error is received while building
services/std_svc/psci/psci_common.c: In function 'psci_do_state_coordination':
services/std_svc/psci/psci_common.c:220:27: error: array subscript is above
array bounds [-Werror=array-bounds]
  psci_req_local_pwr_states[pwrlvl - 1][cpu_idx] = req_pwr_state;

Patch 555ebb34db8f3424c1b394df2f10ecf9c1f70901 explains why the error
is seen and supposibly includes a fix. As the fix appears not to work,
let's disable the error checking.
