msm: pil-riva: Apply resets properly for restart
The Riva processor has two registers to control the cCPU resets.
An override enable register and an override value register.
Program the override enable register so that the override value
setting takes effect. Otherwise the reset may not actually be
applied.
Similarly apply a full reset to the whole processor by asserting
the top level reset (RIVA_RESET). This ensures that the registers
are reset to a known state.
