xtensa: allow dynamic configuration
Import include/xtensa-dynconfig.h that defines XCHAL_* macros as fields
of a structure returned from the xtensa_get_config_v<x> function call.
Define that structure and fill it with default parameter values
specified in the include/xtensa-config.h.
Define reusable function xtensa_load_config that tries to load
configuration and return an address of an exported object from it.
Define functions xtensa_get_config_v{1,2} that use xtensa_load_config
to get structures xtensa_config_v{1,2}, either dynamically configured
or the default.
