ARM: mx7: psci: fix suspend/resume e10133 workaround
The e10133 workaround was broken in two places:
- The code intended to temporarily mask all interrupts in GPC_IMRx_CORE0.
While the old register values were saved, the actual masking was
missing.
- imx_udelay() expects the system counter to run at its base frequency,
but the system counter is switched to a lower frequency earlier in
psci_system_suspend(), leading to a much longer delay than intended.
Replace the call with an equivalent loop (linux-imx 5.15 does the same)
This fixes the SoC hanging forever when there was already a wakeup IRQ
pending while suspending.
Fixes: 57b620255e ("imx: mx7: add system suspend/resume support")
