power: qpnp-fg-gen4: Allow delta MSOC/BSOC threshold configuration for 0.5% 



Currently, delta MSOC/BSOC threshold can be configured from 1 to
12 %. However, it can be configured in 0.5 % increments. This is
useful when SOC (State of Charge) required to be monitored more
accurately. Allow this configuration by changing the parameter to
be specified in deci-percentage unit (e.g. 10 is 1 %).

While at it, print the raw value of MSOC when delta MSOC
interrupt fires.
