plat/st: do not rely on tainted value for dt property length

To compare the "okay" string of a property, strncmp is used but with the
length given by fdt_getprop. This len value is reported as tainted by
Coverity [1]. We just can use strlen("okay") which is a known value
to compare the 2 strings.

- STM32MP157: Dual Cortex-A7 cores, Cortex-M4 core @ 209 MHz,
3D GPU, DSI display interface and CAN FD
- STM32MP153: Dual Cortex-A7 cores, Cortex-M4 core @ 209 MHz
and CAN FD
- STM32MP151: Single Cortex-A7 core, Cortex-M4 core @ 209 MHz

Each line comes with a security option (cryptography & secure boot)
& a Cortex-A frequency option :

- A Basic + Cortex-A7 @ 650 MHz
- C Secure Boot + HW Crypto + Cortex-A7 @ 650 MHz
- D Basic + Cortex-A7 @ 800 MHz
- F Secure Boot + HW Crypto + Cortex-A7 @ 800 MHz

And from crash_console_flush.

We ignore the error information return by console_flush in _every_
place where we call it, and casting the return type to void does not
work around the MISRA violation that this causes. Instead, we collect
the error information from the driver (to avoid changing that API), and
don't return it to the caller.
