Subject: [PATCH] i2c: I2C_DESIGNWARE_AMDISP should depend on DRM_AMD_ISP

The AMD Image Signal Processor I2C functionality is only present on AMD
platforms with ISP support, and its platform device is instantiated by
the AMD ISP driver.  Hence add a dependency on DRM_AMD_ISP, to prevent
asking the user about this driver when configuring a kernel that does
not support the AMD ISP.

Fixes: 63f0545cb1bf0840 ("i2c: amd-isp: Add ISP i2c-designware driver")
