IKXCLOCK-2630 serial: Failed to hit offmode due to UART1 being non-idle
When c55 driver is changing pad configuration than PRCM detects
wake event from pad and it happens after PRCM get suspended
Evidence of this behavior is line:
"omap34xx_do_sram_idle: OMAP3_PRM_IRQENABLE_MPU_OFFSET 0x00000000"
and status bit in:
PRM__CORE (48004a00) b0 => 0x00002000 0x00000000)
As result event still pending and system can not get into requested
low power state.
UART1 is not wakeup-capable and to avoid this false wake ups the wakeup
event has to be disabled in all levels (uart module and PRCM module).
