Subject: [PATCH RESEND 4/4] mfd: tps65090: remove suspend/resume callbacks

The tps65090 mfd driver implement the suspend/resume callbacks
which just disable and enable irqs in suspend/resume respectively.

This operation is already done in irq suspend and irq_resume and
hence it is not require to implement the same in the driver.

Remove this non-require code.

---
This change is based on Mark Brown's comment when reviewing tps80031 mfd driver
as we do not need suspend/resume just for disabling/enabling interrupts.

Resending the patch wth Mark Acks.
