NIOS2: fix kconfig unmet dependency warning for SERIAL_CORE_CONSOLE

SERIAL_CORE_CONSOLE depends on TTY so EARLY_PRINTK should also
depend on TTY so that it does not select SERIAL_CORE_CONSOLE
inadvertently.

WARNING: unmet direct dependencies detected for SERIAL_CORE_CONSOLE
  Depends on [n]: TTY [=n] && HAS_IOMEM [=y]
  Selected by [y]:
  - EARLY_PRINTK [=y]

          This is useful for kernel debugging when your machine crashes very
          early before the console code is initialized.
          You should normally say N here, unless you want to debug such a crash.
