pinctrl: sh-pfc: checker: Add check for enum ID conflicts

Browse source

Add a helper to verify that enum IDs are unique, and use it to validate
the enum ID arrays in config register descriptors.

This exposes bugs like those fixed in:
  - commit 805f635703 ("pinctrl: sh-pfc: r8a7778: Fix duplicate
    SDSELF_B and SD1_CLK_B"),
  - commit 884caadad1 ("pinctrl: sh-pfc: sh7734: Fix duplicate
    TCLK1_B"),
  - commit 2a069a9281 ("pinctrl: sh-pfc: sh7264: Fix Port K I/O
    Register 0 definition").
