Subject: [PATCH 2/2] serial: 8250_ingenic: allow to be independent of SERIAL_8250_CONSOLE

This UART driver should not depend on the console.  They should be
orthogonal.

Surround the earlycon code with CONFIG_SERIAL_EARLYCON conditional
and rip off "depends on SERIAL_8250_CONSOLE".

Currently, SERIAL_8250_FSL also depends on SERIAL_8250_CONSOLE,
but I doubt its necessity.
