Define FMC2 base address, for use in board files, until there is an actual FMC2 bus driver.

For me, the address should be defined in this file only for the few addresses used before device tree avaibility: I want to avoid to have all the device defined here.
But normally it is not the case for FMC2, even if I understand the current need, without FMC2 bus driver.... I will take this patch only it is not possible to get FMC2 address from device tree.
I can parse this information from the DT, but what would be the benefit? Slower boot due to the need to traverse DT and more complex code?
