gpu: host1x: Refactor channel allocation code
This is largely a rewrite of the Host1x channel allocation code, bringing
several changes:
- The previous code could deadlock due to an interaction
between the 'reflock' mutex and CDMA timeout handling.
This gets rid of the mutex.
- Support for more than 32 channels, required for Tegra186
- General refactoring, including better encapsulation
of channel ownership handling into channel.c
