HID: i2c-hid: add more DRM dependencies

When a symbol is selected that has extra dependencies,
anything that selects it must have the same dependencies.
With the added CONFIG_DRM reference from I2C_HID_CORE,
this broke a couple of drivers that now also depend
on DRM:

WARNING: unmet direct dependencies detected for I2C_HID_CORE
  Depends on [m]: HID_SUPPORT [=y] && I2C_HID [=y] && (DRM [=m] || !DRM [=m])
  Selected by [y]:
  - I2C_HID_OF [=y] && HID_SUPPORT [=y] && I2C_HID [=y]
  - I2C_HID_ACPI [=y] && HID_SUPPORT [=y] && I2C_HID [=y] && ACPI [=y]
  - I2C_HID_OF_GOODIX [=y] && HID_SUPPORT [=y] && I2C_HID [=y] && OF [=y]
x86_64-linux-ld: vmlinux.o: in function `i2c_hid_core_remove':
(.text+0xfc8826): undefined reference to `drm_panel_remove_follower'
x86_64-linux-ld: vmlinux.o: in function `i2c_hid_core_probe':
(.text+0xfc8da0): undefined reference to `drm_is_panel_follower'

Add the corresponding DRM||!DRM dependencies on each one that
is affected.
