i2c_msm: Make remote locking backwards compatible with older modem

Older modem for 8x50 (rev 5.0) uses remote lock to change shared flag
variable only. The shared variable's value indicates if a processor
is using I2C bus.
This commit makes the locking compatible with this mechanism.

Revert "usb: msm_otg: Keep the HSUSB3.3V always power on for all targets"

This reverts commit e9259ad3321fcfe0ab8cbe4bfc6d55a636a73cff.

This commit is causing an increase in system current by 4/5mA by
keeping boost voltage regulator always on. Soon will upload a
separate change to address PHY HW teams concerns.
