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 Signed-off-by: Mikko Perttunen <mperttunen@nvidia.com> Reviewed-by: Dmitry Osipenko <digetx@gmail.com> Tested-by: Dmitry Osipenko <digetx@gmail.com> Signed-off-by: Thierry Reding <treding@nvidia.com>
