[PATCH 1/5] Input: aw86927 - fix the 7 V boost reference for AW86938

[Qianhui Xu]

AW86938_PLAYCFG1_BST_7000MV names 7 V, but the register encodes the boost
voltage as ((mV - 6000) / 2 * 0x8313) >> 22 + 5, so the value used since
AW86938 support was added, 0x11, selects 9 V.  Program 0x09 for 7 V, the
value the vendor driver uses for these actuators.

Found while adding the AW86937 variant, which shares the register layout
and the same wrong value.
