Subject: [PATCH] [v2] spi: dw_bt1: fix MUX_MMIO dependencies

From: Arnd Bergmann <arnd@...db.de>

Selecting a symbol with additional dependencies requires
adding the same dependency here:

WARNING: unmet direct dependencies detected for MUX_MMIO
  Depends on [n]: MULTIPLEXER [=y] && OF [=n]
  Selected by [y]:
  - SPI_DW_BT1 [=y] && SPI [=y] && SPI_MASTER [=y] && SPI_DESIGNWARE [=y] && (MIPS_BAIKAL_T1 || COMPILE_TEST [=y])

Drop the 'select' here to avoid the problem. Anyone using
the dw-bt1 SPI driver should make sure they include the
mux driver as well now.

Fixes: 7218838109fe ("spi: dw-bt1: Fix undefined devm_mux_control_get symbol")
Fixes: abf00907538e ("spi: dw: Add Baikal-T1 SPI Controller glue driver")
