Subject: [PATCH v2] gpu: host1x: use dev_err_probe() in probe path

Use dev_err_probe() helper as recommended by core driver model in
drivers/base/core.c to handle deferred probe error. Improve code
consistency and debuggability using standard helper.

Signed-off-by: Akhilesh Patil <akhilesh@...iitb.ac.in>

V1 -> V2: addressed review comments as below.
* inline - err = PTR_ERR(host->clk) inside dev_err_probe()
* avoid printing err, as dev_err_probe() prints it internally.
* rebase and compile test with v6.17-rc2
