[SRU][Q][PATCH 8/9] drm/i915/display: Remove unused declarations of intel_io_*

[AceLan Kao]

From: Gustavo Sousa <gustavo.sousa at intel.com>

BugLink: https://bugs.launchpad.net/bugs/2131066

Declarations for both intel_io_mmio_fw_write and intel_io_reg_write
were added with commit 01389846f7d6 ("drm/i915: Plumb 'dsb' all way to
the plane hooks"), but they never got used. Let's remove them.
