i965: Fix fast depth clear values on Broadwell.
Broadwell's 3DSTATE_CLEAR_PARAMS packet expects a floating point value
regardless of format. This means we need to stop converting it to
UNORM.
Storing the value as float would make sense, but since we already have a
uint32_t field, this patch continues shoehorning it into that. In a
sense, this makes mt->depth_clear_value the DWord you emit in the
packet, rather than the clear value itself.
