[PATCH] clk: qcom: videocc-sm8350: use HW_CTRL_TRIGGER for vcodec GDSCs

[Johan Hovold <johan+linaro@kernel.org>]

A recent change in the venus driver results in a stuck clock on the
Lenovo ThinkPad X13s, for example, when streaming video in firefox:

	video_cc_mvs0_clk status stuck at 'off'
	WARNING: CPU: 6 PID: 2885 at drivers/clk/qcom/clk-branch.c:87 clk_branch_wait+0x144/0x15c
	...
	Call trace:
	 clk_branch_wait+0x144/0x15c
	 clk_branch2_enable+0x30/0x40
	 clk_core_enable+0xd8/0x29c
	 clk_enable+0x2c/0x4c
	 vcodec_clks_enable.isra.0+0x94/0xd8 [venus_core]
	 coreid_power_v4+0x464/0x628 [venus_core]
	 vdec_start_streaming+0xc4/0x510 [venus_dec]
	 vb2_start_streaming+0x6c/0x180 [videobuf2_common]
	 vb2_core_streamon+0x120/0x1dc [videobuf2_common]
	 vb2_streamon+0x1c/0x6c [videobuf2_v4l2]
	 v4l2_m2m_ioctl_streamon+0x30/0x80 [v4l2_mem2mem]
	 v4l_streamon+0x24/0x30 [videodev]

using the out-of-tree sm8350/sc8280xp venus support. [1]

Update also the sm8350/sc8280xp GDSC definitions so that the hw control
mode can be changed at runtime as the venus driver now requires.

Fixes: ec9a652e5149 ("venus: pm_helpers: Use dev_pm_genpd_set_hwmode to switch GDSC mode on V6")
