ASoC: rockchip: spdif: Restore regcache cache-only mode on sync failure

Browse Source 
If regcache_sync() fails during runtime resume, the driver disables the
clocks and returns an error. However, the regmap cache-only mode is left
disabled.
Restore cache-only mode in the error path so subsequent register accesses
continue to use the cache while the device is inactive.
