Eduardo Habkost 38688fdbe9 rx: Rename QOM type check macros
Currently we have a RXCPU typedef and a RXCPU type checking
macro, but OBJECT_DECLARE* would transform the RXCPU macro into a
function, and the function name would conflict with the typedef
name.

Rename the RXCPU* QOM type check macros to RX_CPU*, so we will
avoid the conflict and make the macro names consistent with the
TYPE_RX_CPU constant name.

This will make future conversion to OBJECT_DECLARE* easier.
