Update FreeRTOSconfig.h for M2351 (#1005)
The number of implemented priority bits for Armv8-M baseline
implementation is defined by the architecture as 2. Therefore the
config option `configPRIO_BITS` is updated to 2.
In addition, in Armv8-M baseline implementation BASEPRI is RES0.
Therefore, `configMAX_SYSCALL_INTERRUPT_PRIORITY` is not supported. Hence
this config option is removed.
