ARM: OMAP2+: craneboard: support the TPS65910 PMU
This patch supports the TPS65910 PMU function on the AM3517 Craneboard.
The IRQ pin, SYS_NIRQ is dedicated connection between the AM3517 and
the TPS65910 PMU.
To handle the PMU IRQs, mux configuration is required.
Platform data configuration:
.IRQ number : SYS_NIRQ (M_IRQ_7)
.External clock source : external 32KHz clock is connected
