Subject: [PATCH] pmdomain: mediatek: set default off flag for MT8195 AUDIO
 power domain

In MT8195 power domain data array, set the KEEP_DEFAULT_OFF and
ACTIVE_WAKEUP flags for the AUDIO power domain entry to avoid
having this domain being on during boot sequence when unneeded.

Fixes: 0e789b491ba0 ("pmdomain: core: Leave powered-on genpds on until sync_state")
Fixes: 13a4b7fb6260 ("pmdomain: core: Leave powered-on genpds on until late_initcall_sync")
Signed-off-by: Louis-Alexis Eyraud <louisalexis.eyraud@...labora.com>

Patch tested on Mediatek Genio 1200-EVK board (based on MT8395 SoC)
