ARM: dts: at91: sam9x5: Fix the memory range assigned to the PMC
The memory range assigned to the PMC (Power Management Controller) was not including the PMC_PCR register which are used to control peripheral clocks. This was working fine thanks to the page granularity of ioremap(), but started to fail when we switched to syscon/regmap, because regmap is making sure that all accesses are falling into the reserved range.
