sunxi-6.18: fix H3/H5 RCU stall / CPU hang during DVFS

Disable the megous aw-opp-6.18 patch 0002 ("Don't use CPU PLL gating and
CPUX reparenting to HOSC") on the current (6.18) kernel.

That patch removes two CPU-clock safety notifiers from ccu-sun8i-h3.c:
  - sun8i_h3_pll_cpu_nb  - gates pll_cpux across rate changes so it relocks
                           cleanly
  - sun8i_h3_cpu_nb      - reparents the CPU to the 24 MHz oscillator while
                           pll_cpux is being reprogrammed, then switches back

Without them the core keeps executing off pll_cpux while the PLL is mid
relock. On 6.18 the sunxi clk core was refactored (round_rate ->
determine_rate in ccu_nkmp, ccu_mp rework), and that live PLL change now
glitches the CPU at the first cpufreq/DVFS transition -> core hang -> RCU
stall. It manifests right after thermal zone init (when the governor starts
scaling) and bricks boot on H3/H5 boards.

The patch is identical on legacy 6.12, which boots fine - the difference is
purely the 6.18 clk-core rework, so this is an interaction regression, not a
patch that stopped applying. Leaving 0002 unapplied restores upstream's
notifiers (the 6.12 behaviour) and is the minimal, conservative fix; the OPP
tables and 0001 (max P/M=1) are untouched.

Edge (aw-opp-7.0) is unaffected: it applies 0002 but then reverts it via
0012 and refines with 0013/0008, so the notifiers are already present there
- it must NOT disable 0002 (0012 would have nothing to revert).

Confirmed on hardware: orangepizeroplus (H5) now boots normally on current.
