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.
