[PATCH v2 3/4] drm/imagination: Rename FW booted to FW initialised

[Brajesh Gupta]

Rename the variable from 'booted' to 'initialised' to align with the
driver's expectations and state, indicating that FW boot initialisation
is complete and the firmware is fully initialised.

and pvr_power_fw_enable() function calls, dropping the third argument.

I've just posted a patch to fix this.

[PATCH v2 4/4] drm/imagination: Access FW initialised state with READ/WRITE_ONCE

[Brajesh Gupta]

Update FW initialised state shared resource access with READ/WRITE_ONCE
to prevent following:
- Non-atomic access to variable in multi-thread/CPU case.
- Merge successive loads from the same variable.
