phy: Add drivers for PCIe and SATA phy on SPEAr13xx
ARM based ST Microelectronics's SPEAr1310/40 platforms uses ST's phy (known as 'miphy') for PCIe and SATA. This patch adds drivers for these miphys. This also adds proper bindings for miphys.

+ST SPEAr miphy DT details
+ST Microelectronics SPEAr miphy is a phy controller supporting PCIe and SATA.
+- compatible : should be "st,spear1310-miphy" or "st,spear1340-miphy"
+- reg : offset and length of the PHY register set.
+- misc: phandle for the syscon node to access misc registers
+- #phy-cells : from the generic PHY bindings, must be 1.
+ - cell: 0 if phy used for SATA, 1 for PCIe.
+- phy-id: Instance id of the phy. Only required when there are multiple phys
+ present on a implementation.
