Platform/RPi3: Enable the use of DualSerialPortLib
Note that, for the time being, the TF-A binary only outputs to the
miniUART, but work is underway to add runtime UART detection to TF-A,
after which we will use such a binary.
Also note that this patch currently enforces the use of miniUART in
the ACPI tables, as we have to pick one until we can switch to using
DynamicTablesPkg/ConfigurationManagerDxe for ACPI generation.

+ Additionally, if you want to use PL011 instead of the miniUART, you can add the lines:
+ ```
+ device_tree_address=0x20000
+ device_tree_end=0x30000
+ device_tree=bcm2710-rpi-3-b[-plus].dtb
+ dtoverlay=miniuart-bt

5. Insert the uSD card and power up the Pi.
Note that if you have a model 3+ or a model 3 where you enabled USB boot through OTP
