drivers/mfd/asic3.c:724:2: error: unknown field 'set_pwr' specified in initializer

Rather then open coding a cache of the vibra control registers use the
regmap cache code.  Also cache the interrupt mask register, providing
a small performance improvement for the interrupt code.

        25 ... 52: uV = (vsel - 24) * 50000 + 1500000;
                      = (vsel - 25) * 50000 + 1550000;
        53 ... 55: uV = (vsel - 52) * 100000 + 2900000;

        9  ... 13: uV = (vsel - 8) * 100000 + 1900000;
                      = (vsel - 9) * 100000 + 2000000;
        14 ... 31: uV = (vsel - 13) * 50000 + 2400000;

The voltage tables are composed of linear ranges.
This patch converts this driver to use multiple linear ranges APIs.

In original code, voltage range for DCDC1 is 900000 ~ 1800000 and voltage range
for DCDC3 is 900000 ~ 1500000.  This patch separates the range 25~52 in
tps65217_uv1_ranges table to two linear ranges: 25~30 and 31~52.
This change makes it possible to reuse the same linear_ranges table for DCDCx.

The default phase can meet most cards' requirement, but it is not the
optimal one. In some extreme situation, the rx phase point produced by
the following tuning process will drift quite a distance.
Before tuning UHS card, this patch will set a more proper initial tx
phase point, which is calculated from statistic data, and can achieve
a much better tx signal quality.
