ACPI: EC: make EC support compile-time conditional
The embedded controller code is mainly used on x86 laptops and cannot
work without PC style I/O port access.
Make this a user-visible configuration option that is default enabled
on x86 but otherwise disabled, and that can never be enabled unless
CONFIG_HAS_IOPORT is also available.
The empty stubs in internal.h help ignore the EC code in configurations
that don't support it. In order to see those stubs, the sbshc code also
has to include this header and drop duplicate declarations.
All the direct callers of ec_read/ec_write already had an x86
dependency and now also need to depend on APCI_EC.
