[PATCH v2 2/2] arm64: dts: allwinner: Add SPC Glee 10.1 A64

[Juan Carlos Gutiérrez Lavado via B4 Relay]

From: Juan Carlos Gutiérrez Lavado <jcarlosgl96@xxxxxxxxx>

Add support for the SPC Glee 10.1 tablet based on the Allwinner A64.
Describe the 2 GiB DRAM configuration, AXP803 PMIC, essential supplies,
microSD, UART, battery monitoring and USB peripheral port. Leave eMMC
and unverified peripherals disabled.

Include CPU operating points for frequency scaling and thermal cooling.
Enable the PMIC USB supply and connect it to the PHY for VBUS detection.
Keep the ALDO2 VCC-PL and ALDO3 VCC-PLL/AVCC supplies enabled, matching
the stock firmware and the measured 1.8 V and 3.0 V baseline settings.

Tested with kexec into Linux 7.3.0-rc1 without regulator_ignore_unused:
CPU frequency transitions, CPU cooling frequency cap, and USB supply
unplug/replug detection with SSH reconnection. Cold-boot validation of
this revision remains pending.
