drivers: Implement semihosting based console driver for log

Implement a simple console driver which uses semihosting operations to
read/write the trace messages. There are two paths to output the trace
messages:
- If the caller of semihosting_console_init() provides the path of the
file, the driver will try to open that file, and output the log to
that host side file.
- If the caller of semihosting_console_init() does not provide the path
of the file, the driver will connect the console to the host debug
console directly.

If CFG_SEMIHOSTING_CONSOLE is enabled, OP-TEE will try to initialize the
semihosting console driver by given CFG_SEMIHOSTING_CONSOLE_FILE.

drivers: clk: Add clock duty cycle

Implement reading a clock duty cycle with new clock API function
clk_get_duty_cycle() and clock operation handle ::clk_get_duty_cycle.
When a clock does not provide the operation, it is assumed that the clock
has a 50% duty cycle.

Clock duty cycle information is used for example for some analog-digital
conversion peripheral. This new API function is also expected to be used
by SCMI clock service introduced in the SCMI specification v3.2 [1]
this allow to expose duty cycle service to SCMI clients.

Add support to configure PPI interrupts (assigning to Secure Group 1
etc). Since PPIs are per CPU interrupts as SGIs their configuration
should be synchronized to all CPUs in the same way. Add support to
synchronize needed PPI configuration to other CPUs.

The configuration that needs to be synchronized to other CPUs should
ideally not be changed once the primary CPU has booted. So add a check
in gic_op_enable() to catch this.
