[PATCH 0/7] K2G: Add QSPI support

[Vignesh R]

This series adds support for Cadence QSPI for 66AK2G SoC. The first
three patches enhance the cadence-quadspi driver to support loopback
clock and pm_runtime and tweaks for 66AK2G SoC. Remaining patches add
DT nodes and enable the driver in defconfig.

Tested on 66AK2G GP and ICE boards.
