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

[thomas <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.

Rebase from v7.0.0-rc6 onto v7.0.0-rc7.

Please apply.
