[v10,0/12] Add mt7629 and fix mt7628 pwm

Message

Changes since v10
  1. Follow reviewers's comments:
  - derive the number of PWMs from the specific compatible string
  2. Add mt7629 pwm description
  3. Add mt7628 fixed-clock description

Changes since v9:
  1. PATCH 03/11: Add an Acked-by tag

Changes since v8:
  1. Fix warning and build-error for patch 04/11

Changes since v7:
  1. PATCH v7 10/11: Add a missed Reviewed-by tag

Changes since v6:
  1. Due to we can use fixed-clock in DT
     We removed has_clks and fixed-clock properties 

Changes since v5:
- Follow reviewer's comments:
  1. the license stuff is a separate change
  2. split fix mt7628 pwm into a single patch
  3. to ensure to not use mtk_pwm_clk_name[10] 
     (After dynamic allocate clock array patch, 
      this is no need to check)
  4. Use clock-frequency property to replace 
     the use of has_clks

Changes since v4:
- Follow reviewer's comments (v3: pwm: mediatek: add a property "num-pwms")
  Move the changes of droping the check for of_device_get_match_data
  returning non-NULL to next patch
- Follow reviewers's comments 
  (v3: pwm: mediatek: allocate the clks array dynamically)
  1. use pc->soc->has_clks to check clocks exist or not.
  2. Add error message when probe() unable to get clks
- Fixes bug when SoC is old mips which has no complex clock tree.
if clocks not exist, use the new property from DT to apply period 
calculation; otherwise, use clk_get_rate to get clock frequency and 
apply period calculation.

Changes since v3:
- add a new property "clock-frequency" and fix mt7628 pwm
- add mt7629 pwm support

Changes since v2:
- use num-pwms instead of mediatek,num-pwms.
- rename the member from num_pwms to fallback_num_pwms to make it 
  more obvious that it doesn't represent the actually used value.
- add a dev_warn and a expressive comment to help other developers 
  to not start adding num_pwms in the compatible_data.

Changes since v1:
- add some checks for backwards compatibility.
