bsp/raspberrypi: Fix size of work area.

Browse Source 
The BSP tried to get the size of the SDRAM based on the revision code.
Unfortunately the code had some bugs so that the default size has been
used. Beneath that the MMU table hasn't been adapted.

This patch queries the SDRAM size via a special VC Mailbox call instead.
For the MMU adaption a simmilar method to the one in the imx BSP is
used.
