Description

[mips/broadcom]: Replace static frequency table with generic PMU clock
handling.

  • Extended PWRCTL/PMU APIs to support querying clock frequency during very early boot, prior to bus attach.
  • Implement generic PMU-based calculation of UART rclk values.
  • Replaced use of static frequency tables (bcm_socinfo) with runtime-determined values.
