With this, the UART console has its own initialization which is not dependent on UART init routines. This will allow the app to utilize all UARTs for other purposes, instead of always reserving one for console. Future patch will enable this choice. Note that the console init is effectively demoted to pure_init from pure_early_init. The UART console depends on UART being initialized, but there is no deferred init at this point. So this initializes the console a bit later than UARTs, simply to make sure the UART is initialized before using it. Once there is a mechanism for some type of deferred initialization, the UART console init can be promoted back to pure_early.
