fix(versal): kernel QEMU boot is failing on versal platform

Due to deprecation of VERSAL_PLATFORM build argument,
the board detection is done at runtime due to this the cpu
and uart clock freq was not set as required to silicon values.

Updated Versal QEMU cpu_clock and uart_clock to silicon values.
