[PATCH v7 4/9] iio: ssp_sensors: factor out mcu enable/disable helper(s)

[Sanjay Chitroda <sanjayembeddedse@gmail.com>]

From: Sanjay Chitroda <sanjayembeddedse@gmail.com>

Re-factor the enable and disable MCU logic into small helper functions
this simplify transfer flow to follow.

No functional change intended.
