Subject: [PATCH 0/3] gpu: host1x: Add syncpoint base support

The host1x driver uses currently syncpoints statically from host1x point of
view. If we do a wait inside a job, it always has a constant value to wait.
host1x supports also doing relative syncpoint waits with respect to syncpoint
bases. This allows doing multiple operations inside a single submit and
waiting an operation to complete before moving to next one.

This set of patches adds support for syncpoint bases to host1x driver and
enables the support for gr2d client. The series is based on 3.12-rc4.

I have tested the series using the host1x test application (available at [0],
function test_wait_base() in tests/tegra/host1x/tegra_host1x_test.c) on cardhu.
I would appreciate help in reviewing the series and testing the patches
on other boards.
