PATCH 1/1 ARM: mach-shmobile: sh7377 Enable SDIO IRQs

From: Magnus Damm <[email protected]>

This patch enables interrupt generation for SDIO IRQs of the SDHI block on the sh7377 aka G4 processor. Use together with a recent SDHI driver using TMIO_MMC_SDIO_IRQ and with the MMC_CAP_SDIO_IRQ flag in the board code.

The G4EVM specific SDHI platform data is also updated to flag SDIO capabilities.
