2019-05-08x86: broadwell: Move init of debug UART to cpu.cSimon Glass2-11/+13
At present the debug UART is set up in sdram.c which is not the best place since it has nothing in particular to do with SDRAM. Since we want to support initing this in SPL too, move it to a common file.

2019-05-08x86: broadwell: Allow SDRAM init from SPLSimon Glass3-94/+101
At present, for broadwell, SDRAM is always set up in U-Boot proper since the 64-bit mode (which uses SDRAM init in SPL) is not supported. Update the code to allow SDRAM init in SPL instead so that U-Boot proper can be loaded into SDRAM and run from there. This allows U-Boot to be compressed to reduce space, since it is not necessary to run it directly from flash. It could later allow us to support 64-bit U-Boot on broadwell.

The i8254 timer control IO port (0x43) should be setup correctly by using PIT counter 2 to generate beeps, however in U-Boot other codes like TSC driver utilizes PIT for TSC frequency calibration and configures the counter 2 to a different mode that does not beep.
