fix(msm8916): add timeout for crash console TX flush

Resetting the UART DM controller while there are still remaining
characters in the FIFO often results in corruption on the UART receiver
side. To avoid this the msm8916 crash console implementation tries to
wait until the TX FIFO is empty.

Unfortunately this might spin forever if the transmitter was disabled
before it has fully finished transmitting. In this case the TXEMT bit
console_uartdm_core_flush is waiting for will never get set.

There seems to be no good way to detect if the transmitter is actually
enabled via the status registers. However, the TX FIFO is fairly small
and should not take too long to get flushed, so fix this by simply
limiting the amount of iterations with a short timeout.

Move the code to console_uartdm_core_init to ensure that this always
happens before resetting the transmitter (also during initialization).

fix(msm8916): print \r before \n on UART console

UART drivers in TF-A are expected to print \r before \n. Some terminal
emulators expect \r\n as line endings by default so not doing this

feat(msm8916): initial platform port

Introduce the bare mimimum base of the msm8916 BL31 port. This is
pretty much just a standard platform "skeleton" with CPU/memory
initialization and an UART driver. This allows booting into
e.g. U-Boot with working UART output.

Note that the plat/qti/msm8916 port is completely separate and does not
make use of anything in plat/qti/common at the moment. The main reason
for that is that plat/qti/common is heavily focused around having a
binary "qtiseclib" component, while the MSM8916 port is fully
open-source (and therefore somewhat limited to publicly documented
functionality).

In the future it might be possible to re-use some of the open-source
parts in plat/qti/common (e.g. spmi_arb.c or pm_ps_hold.c) but it's
not strictly required for the basic functionality supported so far.
