[PATCH 4/8] platform/x86: crystal_cove_charger: switch to devm_mutex_init()

[chitranshmandhaniya]

From: Chitransh Mandhaniya <Chitransh_Mandhaniya@xxxxxxxx>

Replace mutex_init() with devm_mutex_init() so the mutex is
automatically destroyed on driver removal via devres.  The driver was
missing a mutex_destroy() call on the teardown path.
