LINFlexD driver was working on S32 based boards without clock management
because the downstream bootloaders (TF-A [1] and U-Boot [2]) were
performing the LINFlexD clock management.

LINFlexD driver from Linux Kernel should manage its clocks independently
and not rely on a previous bootloader configuration.

Changes in V5:
- Use 'devm_add_action_or_reset' to disable LINFlexD clocks if errors
occur on the probe path.

Changes in V4:
- Switched clock management to 'clk bulk' API usage
- Added more context for this patchset

Changes in V3:
- Fixed an error reported by 'dt_bindings_check'

Changes in V2:
- Updated bindings by adding more information related to required
LINFlexD clocks

  dt-bindings: serial: fsl-linflexuart: add clock definitions
  serial: fsl_linflexuart: add clock management
