vx900: Move to EARLY_CBMEM_INIT
To calculate the CBMEM address we need to determine the framebuffer
size early in the ROMSTAGE. We now do the calculation before
cbmem_recovery() and configure the memory controller right away.
If the calculation was done from cbmem_top() instead, we'd loose some
logging that seems useful, since printk() would recurse to cbmem_top() too
with CONSOLE_CBMEM enabled.
If we didn't configure the memory controller at this point, we'd
need to store the result somewhere else. However, CAR_GLOBAL is not
practical at this point, because calling car_get_var() from cbmem_top()
would recurse back to cbmem_top().
