spi: cadence-qspi: defer runtime support on socfpga if reset bit is enabled
[ Upstream commit 30dbc1c8d50f13c1581b49abe46fe89f393eacbf ]
Enabling runtime PM allows the kernel to gate clocks and power to idle
devices. On SoCFPGA, a warm reset does not fully reinitialize these
domains.This leaves devices suspended and powered down, preventing U-Boot
or the kernel from reusing them after a warm reset, which breaks the boot
process.
