[PATCH 2/3] spi: dw-mmio: Add LECARC ACPI ID and init hook

[thomas <thomas_lin@lecomputing.com>]

Add ACPI ID "LECA0002" for LECARC SoCs. This ID requires a custom
initialization function dw_spi_lecarc_init() that sets dws->dws.ip
to DW_HSSI_ID.

Also add corresponding ACPI description in acpi_apd.c.
