CHROMIUM: mfd: max77620: Set num_reg_defaults_rawMYB15I
If num_reg_defaults_raw is unset, regcache will assume the default
value (0x0) for cacheable registers. By setting num_reg_defaults_raw,
regcache_hw_init() will initialize the cache by reading back the values
from hardware and subsequent reads from the cache will correctly reflect
the register values in hardware.
BUG=chrome-os-partner:46750
TEST=Reboot cycle test on Smaug; no hangs seen at boot.
