clk: rockchip: fix incorrect configuration of rk3228 aclk_gpu* clocks The following changes prevent the unrecoverable freezes and rcu_sched stall warnings experienced in each of my attempts to take advantage of lima. Replace the COMPOSITE_NOGATE definition of aclk_gpu_pre with a COMPOSITE that retains the selection of HDMIPHY as the PLL source, but instead makes uses of the aclk_gpu PLL source gate and parent names defined by mux_pll_src_4plls_p rather than mux_aclk_gpu_pre_p. Remove the now unused mux_aclk_gpu_pre_p and the four named but also unused definitions (cpll_gpu, gpll_gpu, hdmiphy_gpu and usb480m_gpu) of the aclk_gpu PLL source gate. Use the correct gate offset for aclk_gpu and aclk_gpu_noc.

clk: rockchip: Fix wrong parent for SDMMC phase clock for rk3228 commit c420c1e4db22 ("clk: rockchip: Prevent calculating mmc phase if clock rate is zero") catches one gremlin again for clk-rk3228.c that the parent of SDMMC phase clock should be sclk_sdmmc0, but not sclk_sdmmc. However, the naming of the sdmmc clocks varies in the manual with the card clock having the 0 while the hclk is named without appended 0. So standardize one one format to prevent confusion, as there also is only one (non-sdio) mmc controller on the soc.

This also unifies the artificial separation of the hclk_vcodec etc clocks again. We do keep the separate definition of some watchdog and usb480m pseudo clocks for now, as they're not real factor clocks from the clock-tree but placeholders for fixes to come (usb480m gets supplied by the missing driver for the new usbphy type and the watchdog-gate is sitting somewhere else together which we cannot model currently).

clk: rockchip: only enter pll slow-mode directly before reboots on rk3288 As commit 1d33929e2a2b ("clk: rockchip: switch PLLs to slow mode before reboot for rk3288") states, switching the PLLs to slow-mode is only necessary when rebooting using the soft-reset done through the CRU. The dwc2 controllers used create really big number of interrupts in special constellations involving usb-hubs and their number is so high, it can even overwhelm the interrupt handler if the cpu-speed os to low. Right now the PLLs are put into slow-mode in a shutdown syscore_ops callback which means it happens on all reboots (not only the soft-reset ones) and even on poweroff actions. This can result in the system not powering off and getting stuck instead, so we should move the slow-mode change nearer to the actual reboot action. For this we introduce the possiblity to also set a callback that gets called from the restart-handler directly prior to restarting the system and move the shutdown-callback to this new option. With this the slow-mode switch is done only on the necessary reboots and also has a smaller possibility of causing artifacts.
