Few fixes for omaps for issues found recently: 

- Fix disable_irq related shared IRQ warnings for omap3 PRM
 
 - Fix omap4 legacy code regression that accidentally removed code that
   we still need for PRM interrupts
 
 - Fix dm8168-evm NAND pins and MMC write protect pin direction
 
 - Fix dra71-evm mdio impedance values
