clk: thead: Fix cpu2vp_clk for TH1520 AP_SUBSYS clocks
...
cpu2vp_clk is a gate but was mistakenly in th1520_div_clks[] instead
of th1520_gate_clks[].

clk: thead: Add CLK_IGNORE_UNUSED to fix TH1520 boot
...
Add the CLK_IGNORE_UNUSED flag to apb_pclk, cpu2peri_x2h_clk,
perisys_apb2_hclk and perisys_apb3_hclk.
Without this flag, the boot hangs after "clk: Disabling unused clocks"
unless clk_ignore_unused is in the kernel cmdline.

clk: thead: Fix clk gate registration to pass flags
...
Modify the call to devm_clk_hw_register_gate_parent_data() to actually
pass the clk flags from hw.init instead of just 0. This is necessary to
allow individual clk gates to specify their own clk flags.

clk: thead: Fix TH1520 emmc and shdci clock rate
...
In accordance with LicheePi 4A BSP the clock that comes to emmc/sdhci
is 198Mhz which is got through frequency division of source clock
VIDEO PLL by 4 [1].
But now the AP_SUBSYS driver sets the CLK EMMC SDIO to the same
frequency as the VIDEO PLL, equal to 792 MHz. This causes emmc/sdhci
to work 4 times slower.
Let's fix this issue by adding fixed factor clock that divides
VIDEO PLL by 4 for emmc/sdhci.

clk: thead: fix dependency on clk_ignore_unused
...
Add the CLK_IGNORE_UNUSED flag to the vp-axi clock (CLK_VP_AXI) to avoid
depending on clk_ignore_unused in the cmdline. Without this fix, the
emmc-sdio clock (CLK_EMMC_SDIO) fails to work after vp-axi is disabled.

clk: T-Head: Disable on 32-bit Targets
...
This fails to build on 32-bit targets because of a missing __udivdi3.
IIRC the right way to fix that is to avoid the division, but I just want
a tree that builds and the only real T-Head platforms are 64-bit right
now.
