clk: imx: replace osc_hdmi with dummy

[ Upstream commit e7fa365ff66f16772dc06b480cd78f858d10856b ]

There is no occurrence of the hdmi oscillator in the reference manual
(document IMX8MNRM Rev 2, 07/2022). Further, if we consider the indexes
76-81 and 134 of the "Clock Root" table of chapter 5 of the RM, there is
no entry for the source select bits 101b, which is the setting referenced
by "osc_hdmi".
Fix by renaming "osc_hdmi" with "dummy", a clock which has already been
used for missing source select bits.

Tested on the BSH SystemMaster (SMM) S2 board.
