imx: console: Use CONSOLE_T_BASE for UART base address

Since commit ac71344e9eca we have the UART base address in the generic
console_t structure. For most platforms the platform-specific struct
console is gone, so we *must* use the embedded base address, since there
is no storage behind the generic console_t anymore.

Replace the usage of CONSOLE_T_DRVDATA with CONSOLE_T_BASE to fix this.
