qualcommax: ipq50xx: prepare for UNIPHY reset fix

Ahead of the actual fix in both the GCC and QCA-SSDK, add the required
AHB reset so it can be picked up by updated QCA-SSDK. This is needed
as the SSDK needs to use different resets depending on the link
architecture. If it's a fixed link, AHB needs to be reset. In a phy to
phy link setup (such as QCA8081), SYS, RX, and TX need to be reset using
one reset with a bitmask in the GCC (GCC_UNIPHY_SOFT_RESET).
