The way hw_onecell_data is declared:
struct clk_hw_onecell_data {
unsigned int num;
struct clk_hw *hws[];
};
makes it impossible to have the clk_hw table declared outside while
using ARRAY_SIZE() to determine ".num" due to ".hws" being a flexible
array member.
Completely move out of hw_onecell_data and add a custom
devm_of_clk_add_hw_provider() "get" callback to retrieve the clk_hw
from the meson_eeclkc_data struct to finally get rid on the
NR_CLKS define.

This adds the MIPI DSI Host Pixel Clock, unlike AXG, the pixel clock can be different
from the VPU ENCL output clock to feed the DSI Host controller with a different clock rate.

This adds the Neural Network Accelerator source clocks hierarchy, it's
2 simple composite clocks to feed the AXI interface and the Core of
the Neural Network Accelerator IP.
This IP is only present on the Amlogic SM1 SoCs family.

This adds the clocks used for the Amlogic G12A and compatible SoCs SPICC
controller to provide a more complete range of frequencies instead of the
SPICC internal divider over Xtal.

The Amlogic SM1 can set a dedicated clock frequency for each CPU core by
having a dedicate tree for each core similar to the CPU0 tree.
Like the DSU tree, a supplementaty mux has been added to use the CPU0
frequency instead.
But since the cluster only has a single power rail and shares a single PLL,
it's not worth adding 3 unsused clock tree, so we add only the mux to
select the CPU0 clock frequency for each CPU1, CPU2 and CPU3 cores.
They are set read-only because the early boot stages sets them to select
the CPU0 input clock.

The Amlogic SM1 DynamIQ Shared Unit has a dedicated clock tree similar to
the CPU clock tree with a supplementaty mux to select the CPU0 clock
instead.
Leave this as read-only since it's set up by the early boot stages.

Add the new GP1 PLL for the Amlogic SM1 SoC, used to feed the new
DynamIQ Shared Unit of the ARM Cores Complex.
This also adds a dedicated set of clock and compatible for SM1.

Update the Meson G12A Clock driver to support the Amlogic G12B SoC.
G12B clock driver is very close, the main differences are :
- the clock tree is duplicated for the both clusters, and the
SYS_PLL are swapped between the clusters
- G12B has additional clocks like for CSI an other components
Here only the cpu clock tree is handled.

Add the necessary clock parts for:
- VDEC_1: used to feed VDEC_1
- VDEC_HEVC: the "back" part of the VDEC_HEVC block
- VDEC_HEVCF: the "front" part of the VDEC_HEVC block
In previous SoC generations (GXL, GXBB), there was only one VDEC_HEVC
clock, which got split in two parts for G12A.

Add the PCIe reference clock feeding the USB3 + PCIE combo PHY.
This PLL needs a very precise register sequence to permit to be locked,
thus using the specific clk-pll pcie ops.
The PLL is then followed by :
- a fixed /2 divider
- a 5-bit 1-based divider
- a final /2 divider
This reference clock is fixed to 100MHz, thus only a single PLL setup
is added.

Add the Amlogic G12A Family CPU Clock tree in read/only for now.
The CPU clock can either use the SYS_PLL for > 1GHz frequencies or
use a couple of div+mux from 1GHz/667MHz/24MHz source with 2 non-glitch
muxes.
Proper DVFS support will come in a second time.
