#1684070 — [PATCH] ata: fix gemini Kconfig dependencies

We cannot build the new ftide010 code without also building the faraday
sata bridge driver:

drivers/ata/pata_ftide010.o: In function `pata_ftide010_probe':
pata_ftide010.c:(.text+0x2b8): undefined reference to `gemini_sata_bridge_get'
pata_ftide010.c:(.text+0x32c): undefined reference to `gemini_sata_get_muxmode'
pata_ftide010.c:(.text+0x358): undefined reference to `gemini_sata_bridge_enabled'
drivers/ata/pata_ftide010.o: In function `pata_ftide010_gemini_port_stop':
pata_ftide010.c:(.text+0x520): undefined reference to `gemini_sata_stop_bridge'
drivers/ata/pata_ftide010.o: In function `pata_ftide010_gemini_port_start':
pata_ftide010.c:(.text+0x5bc): undefined reference to `gemini_sata_start_bridge'

This adjusts the Kconfig dependencies accordingly.

Acked-by: Linus Walleij <linus.walleij@linaro.org>

My intention was definately to have the bridge driver as a separate add-on
as I suspect some systems use the PATA driver without the SATA bridge.

But we can definately deal with that when those users appear.

Yours,
Linus Walleij
