To assist in x86 chipset bringup, there are 4 GPIOs we weren't
printing state transitions for.

TEST=reboot; should see state transitions in the high nibble (mask 0xF000), for example:
[x86 power state 1 = S5, in 0x2001]
[x86 power state 1 = S5, in 0x3001]
[x86 power state 1 = S5, in 0x7001]

Preparatory work to introduce a second SoC : 3rd series 2/2
All the RO/A/B firmware copy code could be generic to all our platforms.
The console commands are a 'standard' API.

Most of the code is handling the buffering and the printf, thus put it
in an hardware independant location and only implement the UART
dependant portions in the chip driver.

You can now enable/disable tasks more easily.
To conditionally compile a C file depending on the task FOO activation,
just write something like that in the build.mk file :

Instead of using a runtime callback to register the console commands,
put them in a special linker section. So we can do a macro to "register"
them during the build.
It saves 684 bytes and a few microseconds at startup.

Implement TPS2543 USB charging control.
It contains routine for setting each USB port as dedicated charging port
or standard downstream port. To allow us controlling the current
distributed to each port, we can select whether to allow 500mA or 1500mA
for each port.

TEST=Added USB port definition for BDS and tested GPIO output voltage
level is correct for all modes.
