6.1-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Kamal Wadhwa <redacted>

[ Upstream commit abd14bebb87e0fa2749371272c8b31d6ee5f0a36 ]

Currently, when `rpmh_regulator_set_mode_bypass()` helper function
is called to set bypass mode, it sends PMIC4's BOB bypass mode
value for even if its a PMIC5 BOB.

To fix this, introduce new hw_data parameter`pmic_bypass_mode`
to store bypass mode value. Use it to send correct PMIC bypass
mode value that corresponds to PMIC4/5 BOB regulators from the
helper function.
