configs: Migrate CONFIG_FMAN_ENET and some related options to Kconfig

Move the main symbol for Freescale Fman Ethernet controller option to
Kconfig.  Also migrate the CONFIG_SYS_QE_FMAN_FW_IN_xxx macros and
rename the SPIFLASH one to follow the same format as all of the others.
To do this fully we need to migrate CONFIG_QC, do so.
