ACPI: EC: Enable EC support on LoongArch by default

Commit a6021aa24f6417416d933 ("ACPI: EC: make EC support compile-time
conditional") only enable ACPI_EC on X86 by default, but the embedded
controller is also widely used on LoongArch laptops so we also enable
ACPI_EC for LoongArch.

The laptop driver cannot work without EC, so also update the dependency
of LOONGSON_LAPTOP to let it depend on APCI_EC.
