[PATCH v7 7/9] crypto: qce: core: Make clocks optional

[Bhupesh Sharma]

From: Thara Gopinath <thara.gopinath@xxxxxxxxx>

On certain Snapdragon processors, the crypto engine clocks are enabled by
default by security firmware and the driver need not/ should not handle the
clocks. Make acquiring of all the clocks optional in crypto engine driver
so that the driver initializes properly even if no clocks are specified in
the dt.
