- Don't mention the reset topology in the lc_ctrl theory of operation doc's
  description of CPU_EN since lc_cpu_en_o is independent of reset, and
  rv_core_ibex gets a separate fetch_en input from pwrmgr that determines
  whether the cpu is effectively enabled.
- Fix the life cycle control description in the rv_dm interfaces doc: all
  it needs to say is that NDM reset will not reset rv_dm but will reset
  lc_ctrl. The prior text is inaccurate.

Fixes lowRISC#20700
