Subject: [PATCH] firmware-qualcomm: generalize bluetooth customizations

Generalize 'Disable Deep Sleep' and 'Enable Internal clock' customizations
so they can be applied on every platform by defining
BT_INTCLOCK_WORKAROUND to '1'.

Disable the customizations by default and enable them for ccimx6ul only.

Signed-off-by: Gonzalo Ruiz <Gonzalo.Ruiz@digi.com>
(cherry picked from commit 78ef498178abe587d6e2cb4b1ed8ba5f8979fb4e)
