serial: sc16is7xx: rename Kconfig CONFIG_SERIAL_SC16IS7XX_CORE

Commit d492164
("serial: sc16is7xx: split into core and I2C/SPI parts (core)")
renamed SERIAL_SC16IS7XX_CORE by SERIAL_SC16IS7XX. This means that some
configs should have been updated when I submitted the original patch, but
unfortunately they were not. Geert mentioned for example:
    arch/mips/configs/cu1??0-neo_defconfig

Rename SERIAL_SC16IS7XX to SERIAL_SC16IS7XX_CORE so that existing configs
will still work correctly.
