common-csl-ip-rtos: drop unnecessary dependency on ti-sysbios
common-csl-ip-rtos: drop unnecessary dependency on ti-sysbios

It appears common-csl-ip-rtos does not require ti-sysbios dependency to build,
but ti-pdk.bbclass adds it by default. While most of PDK-based components do
require ti-sysbios to be built from sources, it is safe to remove it from CSL,
reducing the dependency tree for special cases like PRU FW based on CSL, but
not needing ti-sysbios.

This only affects firmwares built from sources against PDK and CSL, not when
RTOS firmwares are delivered in binary form for newer K3 platforms.

Build-tested on am335x, am57xx, k2g and am65xx.
