[bsp/nxp/mcx/mcxa] Fix UART clock configuration type mismatch

Fixed implicit type conversion warning in UART driver by correctly
separating clock_name_t and clock_attach_id_t enum types.

Changes:
- Use kCLOCK_Fro12M (clock_name_t) for clock_src field
- Keep kFRO12M_to_LPUARTx (clock_attach_id_t) for clock_attach_id field
- Fix mcx_getc() to use correct status flag kLPUART_RxDataRegFullFlag

This resolves the compiler warning:
"implicit conversion from 'int' to 'clock_name_t' changes value from 16777216 to 0"
