hwmon: (pmbus/tps53679) Select page 0 for single-page TPS536C7
tps536c7_identify() sets info->pages to 1 for a single-channel part and
then accesses page 0 (writing PMBUS_PHASE) without ensuring PAGE is
actually 0. pmbus_set_page() does not update the PAGE register when
info->pages is 1, so if boot firmware left PAGE set to another value the
PHASE writes and subsequent telemetry may target the wrong page.
Select page 0 explicitly before configuring PHASE.
