drm/panel: make DRM_PANEL_LD9040 depend on SPI
Rather than DRM_PANEL_LD9040 selecting SPI, which then results in an
increase in the probability of Kconf reporting circular dependencies
(we're one "select" away from that right now), make this depend on
SPI instead. This is akin to having some driver select DRM.
Having some drivers depend on a subsystem, and other drivers select a
subsystem is a recipe for circular dependencies, and there's really no
need for it.
The potential circular dependency (which can be caused today by the
addition of selecting DRM_PANEL from DRM_IMX_LDB) is:
symbol DMADEVICES is selected by SAMSUNG_DMADEV
symbol SAMSUNG_DMADEV is selected by S3C64XX_PL080
symbol S3C64XX_PL080 is selected by SPI_S3C64XX
symbol SPI_S3C64XX depends on SPI
symbol SPI is selected by DRM_PANEL_LD9040
symbol DRM_PANEL_LD9040 depends on DRM_PANEL
symbol DRM_PANEL is selected by DRM_IMX_LDB
symbol DRM_IMX_LDB depends on MFD_SYSCON
symbol MFD_SYSCON is selected by POWER_RESET_KEYSTONE
symbol POWER_RESET_KEYSTONE depends on POWER_SUPPLY
symbol POWER_SUPPLY is selected by HID_SONY
symbol HID_SONY depends on NEW_LEDS
symbol NEW_LEDS is selected by BACKLIGHT_ADP8860
symbol BACKLIGHT_ADP8860 depends on BACKLIGHT_CLASS_DEVICE
symbol BACKLIGHT_CLASS_DEVICE is selected by FB_MX3
symbol FB_MX3 depends on MX3_IPU
symbol MX3_IPU depends on DMADEVICES
