[PATCH] tty: serial: make SERIAL_SPRD depends on ARM or ARM64

[Chunyan Zhang]

From: Chunyan Zhang <chunyan.zhang@xxxxxxxxxx>

kbuild-test reported an error:

  config: mips-randconfig-a001-20200321 ...
  >> drivers/tty/serial/sprd_serial.c:1175: undefined reference
  to `clk_set_parent'

Because some mips Kconfig-s select CONFIG_HAVE_CLK but not CONFIG_COMMON_CLK,
so it's probably that clk_set_parent is missed for those configs.

To fix this error, this patch adds dependence on ARM || ARM64
for SERIAL_SPRD.

Fixes: 7ba87cfec71a ("tty: serial: make SERIAL_SPRD not depend on ARCH_SPRD")
