ARM: at91: fix PM initialization for newer SoCs
Newer SoCs: at91sam9x5, at91sam9n12, sama5d3 and sama5d4 embed a DDR controller and have a different PMC status register layout than the at91sam9g45. Create another at91_sam9x5_pm_init() function to match this compatibility. Signed-off-by: Nicolas Ferre <nicolas.ferre@atmel.com>
