The Mali C55 Iridix block has a digital gain function and tone mapping
function, whose enablement is controlled by two different bits
in the BYPASS_3 register.

Unfortunately, the "Gain" and "Tonemap" bypass bit definitions are the
wrong way around. Swap them so that the ISP is now operated with the
"Iridix Gain" block enabled and default configured at a x1.0 gain and
with the "Iridix Tonemap" disabled, as it was originally intended.

As far as I can see the current upstream driver does not bypass either of them,
so swapping them will have no direct effect.

Where is this commit? I cannot seem to find it.
