Sure, I was not sure so I leaned in the safe bet direction. Squashing is
much easier than splitting. Also improved the commit message, which
will look like this for next revision (incoming soon):

dt-bindings: clock: eyeq: add more Mobileye EyeQ5/EyeQ6H clocks

Add #defines for Mobileye clock controller:

 - EyeQ5 core 0 thru 3 clocks. Internally:

      EQ5C_PLL_CPU:           already exposed
      └── EQ5C_CPU_OCC:       unexposed, no reason to do so
          ├── EQ5C_CPU_CORE0: new!
          ├── EQ5C_CPU_CORE1: new!
          ├── EQ5C_CPU_CORE2: new!
          └── EQ5C_CPU_CORE3: new!

 - EyeQ5 peripheral clocks. Internally:

      EQ5C_PLL_PER:          already exposed
      └── EQ5C_PER_OCC:      new!
          └── EQ5C_PER_UART: new!

 - EyeQ6H central OLB. Internally:

      EQ6HC_CENTRAL_PLL_CPU:     new!
      └── EQ6HC_CENTRAL_CPU_OCC: new!

 - EyeQ6H west OLB. Internally:

      EQ6HC_WEST_PLL_PER:          new!
      └── EQ6HC_WEST_PER_OCC:      new!
          └── EQ6HC_WEST_PER_UART: new!
