This series adds the missing mpll3 parent clock and completes the
Amlogic T7 SoC clock controller DT support.

- Fix redundant hyphen in for gp1 pll
- Add the missing mpll3 parent clock definition to t7-peripherals-clkc.yaml
- Add Amlogic T7 SoC clock controller nodes

Changes in v3 since v2 at [2]:

- Move Ronald's SoB tag to the top (as original author of the base patches)
- Add Krzysztof's Reviewed-by for Patch 2
- Update cover letter structure for clarity

Changes in v2 since v1 at [1]:

- Add Ronald Claveau's Signed-off-by to the first and third patches
- Fix compilation error for amlogic-peripherals-clkc.yaml
- Update commit message for amlogic-peripherals-clkc.yaml
- Add Fixes tag
- Remove the blank line in the watchdog node of meson-t7.dtsi
- Add 'reg' property to sram node
- Add a space after the clock controller label

### Background
This series is based on Ronald's initial T7 clock series [3], which aimed
to enable T7 EMMC DT but lacked a complete clock controller implementation.
The T7 clock tree in Ronald's series (fixed PLL, fixed fdivX and sys clocks)
is handled by the SCP firmware via SCMI [4]. Therefore, his clock drivers
do not need to be added. I have discussed with Ronald and agreed that I
will submit the T7 clock DT first, then he can proceed with his EMMC work.

### Series Overview
1. Patch 1: Fix redundant hyphen in amlogic,t7-pll-clkc DT binding
   - Based on Ronald's "[3/7] dt-bindings: clk: meson: Add Amlogic T7 fix pll support"
2. Patch 2: Add missing mpll3 parent clock definition to t7-peripherals-clkc.yaml
3. Patch 3: Add complete T7 clock controller nodes
   - Based on Ronald's initial PLL and peripheral clock nodes
   - Remove unused fixed PLL node
   - Add PCIe and HDMI PLL nodes
   - Add SCMI clock nodes for clocks handled by SCP firmware
   - Update fixed clock index in peripheral clock nodes
   - Add gp1 and mpll1 clock index in peripheral clock nodes

### Dependencies
- Patch 3 depends on Patch 2

### ABI Risk
The amlogic,t7-peripherals-clkc DT binding was merged in v7.0-rc1 [5],
but the corresponding Amlogic T7 SoC DT has not been submitted upstream
yet. Thus, no real users or systems are affected by the DT binding ABI
breakage in this series.

### Credit
- Patch 1 is based on Ronald's "[PATCH 3/7] dt-bindings: clk: meson: Add Amlogic T7 fix pll support"
- Patch 3 is based on Ronald's "[6/7] arm64: dts: amlogic: Add clock and EMMC for T7"
- Patch 1 and Patch 3 retain Ronald's Signed-off-by
- Thanks to Ronald for pointing out the gp1 pll typo and initial clock work
