[PATCH AUTOSEL 6.8 15/52] ASoC: cs35l41: Update DSP1RX5/6 Sources for DSP config

[Sasha Levin <sashal@kernel.org>]

From: Stefan Binding <sbinding@opensource.cirrus.com>

[ Upstream commit eefb831d2e4dd58d58002a2ef75ff989e073230d ]

Currently, all ASoC systems are set to use VPMON for DSP1RX5_SRC,
however, this is required only for internal boost systems.
External boost systems require VBSTMON instead of VPMON to be the
input to DSP1RX5_SRC.
Shared Boost Active acts like Internal boost (requires VPMON).
Shared Boost Passive acts like External boost (requires VBSTMON)
All systems require DSP1RX6_SRC to be set to VBSTMON.
