That's right. It's the DT which is at the fault of defining spiclk
instead of sspclk and need to be fixed in DT itself. I didn't take a
look at pl022 doc and acted on the basis of DT info.

Moreover, DT also uses sspclk and SSPCLK names interchangeably which are
anyway same. This also require updation to follow single convention.

Appreciate your comments and valuable inputs.
