lib: utils: fdt: Claim Zicntr if time CSR emulation is possible
OpenSBI is capable of emulating time CSR through an external timer
for HARTs that don't implement a full Zicntr extension. Let's add
Zicntr extension in the FDT if CSR emulation is active.
This avoids hardcoding the extension in the devicetree, which may
confuse pre-SBI bootloaders.
