[PATCH v4 0/3] arm64: Add LECARC ACPI IDs for DesignWare GPIO, SPI, I2C

[Thomas Lin <thomas_lin@lecomputing.com>]

This patch series adds ACPI identification for LECARC SoCs that
integrate Synopsys DesignWare peripherals.

LECARC platforms use the following ACPI HIDs:

GPIO: LECA0001 (V1 register offsets)

SPI: LECA0002 (requires custom init function)

I2C: LECA0003

The patches are independent but share a common dependency on the
ACPI description file (acpi_apd.c) for SPI and I2C. To avoid merge
conflicts, they are submitted as a single series with the following
order:

Patch 1: GPIO – add LECA0001 to dwapb_gpio ACPI match table.
Patch 2: SPI – add LECA0002 and dw_spi_lecarc_init() to spi-dw-mmio,
plus corresponding entry in acpi_apd.c.
Patch 3: I2C – add LECA0003 to DesignWare I2C ACPI match table,
plus corresponding entry in acpi_apd.c.

All changes have been tested on LECARC evaluation board with
kernel v7.0.0-rc7. No regressions observed on existing hardware.

Changes since v1:

- Revised subject lines to match subsystem style guidelines
- No functional changes
- All the comments from reviews has been fixed

Changes since v2:
- Wrap long commit description lines to 72 columns
- Fix code indentation in spi-dw-mmio.c: use tabs + spaces for alignment
- No functional changes

Changes since v3:
- Start a new thread for each revision
