board: nios2: Check if flash is configured before calling early_flash_cmd_reset()

If CONFIG_CFI_FLASH_MTD is not defined, then we shouldn't perform the
flash early reset.

This commit fixes the following build error:

  nios2-generic.c: In function `__early_flash_cmd_reset':
  nios2-generic.c:23: error: `AMD_CMD_RESET' undeclared (first use in this function)
  nios2-generic.c:23: error: (Each undeclared identifier is reported only once
  nios2-generic.c:23: error: for each function it appears in.)
  nios2-generic.c:24: error: `FLASH_CMD_RESET' undeclared (first use in this function)

which was introduced by:

  commit a113fb39df43546c704aa8eba55720da9a9dfedd
