[PATCH] media: synopsys: fix link failure against GENERIC_PHY_MIPI_DPHY

[Arnd Bergmann <arnd@kernel.org>]

From: Arnd Bergmann <arnd@arndb.de>

The newly added driver uses the generic mipi dphy driver but is missing
a Kconfig dependency:

ld.lld-22: error: undefined symbol: phy_mipi_dphy_get_default_config_for_hsclk
>>> referenced by dw-mipi-csi2rx.c:240 (/home/arnd/arm-soc/drivers/media/platform/synopsys/dw-mipi-csi2rx.c:240)
>>>               drivers/media/platform/synopsys/dw-mipi-csi2rx.o:(dw_mipi_csi2rx_enable_streams) in archive vmlinux.a

This is in a library module that needs to be selected by each user, so
add the missing 'select' here.

Fixes: 355a11004066 ("media: synopsys: add driver for the designware mipi csi-2 receiver")
