With recent enough motherboard firmware, core tile can be fitted
in either of the two daughterboard sites. The non-DT tile code for
V2P-CA9 did not check that when configuring DVI output nor setting
CLCD pixel clock.

Fixed now, providing "get master site" API in motherboard's code.

This patch makes an Ubuntu boot always hang for me, about the time it
would switch to GUI mode, it's not very consistent unfortunately.

I've found the cause of the problem, v2m_get_master_site() is marked
__init but is used by the non __init function ct_ca9x4_clcd_enable(). So
when Ubuntu GUI startup messes with the display it ends up calling into
freed memory.

Dropping __init from ct_ca9x4_clcd_enable() fixes my boot failures.
