ARM: dts: msm: Move volume up/down configuration to apq8053-lite-som

Remove volume up and down configuration from base apq8053-lite-dragon
based devices and add into apq8053-lite-som based device for supporting
in dev console. This way volume up/down functionality gets enabled for
developers while apq8053-lite-dragon based device variants can expose
the gpio for other purposes using pio hal.

SPMI RESIN interrupt line is responsible for triggering the fastboot
command and doubles as a VOLUME_DOWN pin. For apq8053-lite-dragon based
device variants, in certain use-cases, these keyevents need to be
suppressed and instead, is directly read the line state (high/low)
from user-space. In order to support this, set the `resin-gpiobase`
entry to expose this interrupt line as a virtual GPIO.
