Remove support for Allwinner A80 platform (plat-sunxi)
It has been almost three years since we have heard about plat-sunxi
(no new contributions, no patch ack'ed or tested, no feedback at
release time). Therefore, remove support for this platform.

tzc380: export more api
Introduce tzc_security_inversion_en tzc_enable_region tzc_fail_dump and
tzc_int_clear.
When we want to block secure access to region configured TZC_ATTR_SP_NS_RW,
need to use tzc_security_inversion_en.
Sometimes we need to configure the regions first, then enable the
region.
tzasc380 interrupt could be enabled to catch some illegal access
with tzc_fail_dump and tzc_int_clear.

pl011: prevent putc() and flush() function from blocking indefinitely
It may happen that trace functions are called by OP-TEE when the UART
or its clock is disabled by the non-secure OS. In such a case, flush()
is likely to loop indefinitely, because the UART status register may
never contain the expected value. Make the code more robust by checking
if the UART is enabled in the wait loop. If it is not, or if the status
bit remains zero due to the clock being turned off, return immediately.
By doing so, we allow to drop some output rather than hang the whole
system.

drivers: serial8250_uart: use 32-bit accesses to the uart registers
Due to hardware design, some platforms can't access the peripheral IO
registers once a byte(8-bit) but once a word(32-bit). Obviously, using
32-bit accesses to the registers is more flexible for other plaforms
to use serial8250 uart.
