The "QCA9531 v2.0 802.11n 2x2 2.4 GHz Premium SOC for WLAN Platforms"
datasheet (80-Y7991-1 Rev. C - October 2014) doesn't specify support for a
40 Mhz reference clock. The register description for "Bootstrap Options"
(page 31) defines following states for the bit 4 (REF_CLK):
* 0 - CLK25 (default)
* 1 - (reserved)
Devices like the TP-Link CPE210 v2 has this bit set to 1 but is using a 25
Mhz reference clock. OpenWrt is still interpreted this bit as 40 Mhz and
then break the bootup of the system due to this incorrect interpretation.

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.
