[PATCH v6 05/11] mfd: sec: set DMA coherent mask

[Kaustabh Chakraborty <kauschluss@disroot.org>]

Kernel logs are filled with "DMA mask not set" messages for every
sub-device. The device does not use DMA for communication, so these
messages are useless. Disable the coherent DMA mask for the PMIC device,
which is also propagated to sub-devices.
