[PATCH v2 1/3] arm64: dts: amlogic: t7: Fix pwm_ao_c pinmux definitions

[Ronald Claveau via B4 Relay <devnull+linux-kernel-dev.aliel.fr@kernel.org>]

From: Ronald Claveau <linux-kernel-dev@aliel.fr>

The pwm_ao_c pin node was incomplete: it was missing the group name
suffix, conflating two distinct pin groups (pwm_ao_c_d and pwm_ao_c_e)
into a single, ambiguous entry.

Split the node into two separate pinmux entries:
  - pwm_ao_c_d_pins: uses group "pwm_ao_c_d"
  - pwm_ao_c_e_pins: uses group "pwm_ao_c_e"

Both alternate pins are not yet referenced by any peripheral node,
so this has no functional impact on existing boards. No backport needed.

Fixes: ee6e05a49b93 ("arm64: dts: amlogic: t7: Add PWM pinctrl nodes")
