ar71xx: add AR724x PCIe init fixes

Add upstream send AR724x PCIe patches to get the PCIe controller out of
reset during driver init.

The AVM Fritz 300E bootloader doesn't take care of releasing the
different PCIe controller related resets which causes an endless hang
as soon as either the PCIE Reset register (0x180f0018) or the PCI
Application Control register (0x180f0000) is read from.

+Subject: [PATCH] MIPS: ath79: fix AR724X_PLL_REG_PCIE_CONFIG offset
+
+According to the QCA u-boot source the "PCIE Phase Lock Loop
+Configuration (PCIE_PLL_CONFIG)" register is for all SoCs except the
+QCA955X and QCA956X at offset 0x10.
+
+Since the PCIE PLL config register is only defined for the AR724x fix
+only this value. The value is wrong since the day it was added and isn't
+yet used by any driver.

+Subject: [PATCH] MIPS: pci-ar724x: get PCIe controller out of reset
+
+The ar724x pci driver expects the PCIe controller to be brought out of
+reset by the bootloader.
+
+At least the AVM Fritz 300E bootloader doesn't take care of releasing
+the different PCIe controller related resets which causes an endless
+hang as soon as either the PCIE Reset register (0x180f0018) or the PCI
+Application Control register (0x180f0000) is read from.
+
+Do the full "PCIE Root Complex Initialization Sequence" if the PCIe
+host controller is still in reset during probing.
+
+The QCA u-boot sleeps 10ms after the PCIE Application Control bit is
+set to ready. It has been shown that 10ms might not be enough time if
+PCIe should be used right after setting the bit. During my tests it
+took up to 20ms till the link was up. Giving the link up to 100ms
+should work for all cases.
