[ 0.257415] pinctrl-s700 e01b0000.pinctrl: can't request region for

[ 0.266902] pinctrl-s700: probe of e01b0000.pinctrl failed with error -16
This is due to the fact that memory range for "sps" power domain controller
clashes with pinctrl.
This commit fixes it by disabling "sps" node, it is safe as "sps" is not
being used at the moment.
Fixes: 7cdf8446ed1d ("arm64: dts: actions: Add pinctrl node for Actions
Semi S700")But this is more of a hack than a proper solution, right? Especially since you actually need the SPS later on (patch 8/8). It's probably good enough to prove that the DMA and MMC parts are working, but should not be merged. Cheers, Andre.
