arm64: issue ISB after updating system registers

Reference Manual ARMv8 for ARMv8-A Architecture Profile" (ARM DDI
0487B.a).

Failing to issue instruction synchronization barrier can lead to
spurious errors, like synchronous exception when accessing FPU
registers. This is very prominent on CPUs with long instruction
pipeline, like ARM Cortex A72.

This change fixes the following U-Boot panic:

VREFBUF is used by ADC/DAC on some boards. An overshoot on the reference
voltage make the conversions inaccurate for a short period of time. So:
- Don't put the VREFBUF in HiZ when disabling, to force an active
  discharge.
- Enforce a 1ms OFF/ON delay, also upon reset

Penalty is a 1ms delay is applied (even for a cold boot), when enabling
VREFBUF.
