Zephyr deprecates passing the chip-select delay as the variadic delay argument to SPI_DT_SPEC_INST_GET. Remove that deprecated macro argument from the raw LLCC68 device initializer. Add spi-cs-setup-delay-ns and spi-cs-hold-delay-ns defaults to the custom LLCC68 devicetree binding. Both defaults are 100000 ns, preserving the previous 100 us delay behavior while using the current Zephyr SPI devicetree properties. Verified with cmake -S . -B build and cmake --build build from the parent application.
