ARM: OMAP2+: am43xx: Add lcdc clockdomain 



As described in AM437x TRM, spruhl7h, Revised January 2018, there is
an LCDC clockdomain present in the PER power domain. Although it is
entirely unused on AM437x, it should be defined along with the other
clockdomains so it can be shut off by Linux as there are no users.
