A few more clk driver fixes

Browse Source 
- Set the max_register member of the spreadtrum regmap so that reads
    don't go off the end of the I/O space
 
  - Avoid a clk parent error in the i.MX imx6ul driver when the selector
    is unknown
 
  - Fix an oops due to REGCACHE_NONE usage by the Renesas 9-series driver
