[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 (drivers/acpi/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: dwapb – add LECA0001 to dwapb_acpi_match[].
Patch 2: spi: dw-mmio – add LECA0002 and dw_spi_lecarc_init(),
         plus corresponding entry in acpi_apd.c.
Patch 3: i2c: designware – add LECA0003 to dw_i2c_acpi_match[],
         plus corresponding entry in acpi_apd.c.

All changes have been tested on LECARC evaluation board with
kernel v7.0.0-rc6. No regressions observed on existing hardware.

Please apply.
