fix(llcc68): align spi binding with zephyr

Browse Source 
Add a module-local .gitignore entry for macOS .DS_Store artifacts so generated Finder metadata does not dirty the submodule.

Declare the SPI chip-select delay binding properties as integers so Zephyr devicetree validation accepts the custom LLCC68 binding.

Pass the configured setup delay into SPI_DT_SPEC_INST_GET using the Zephyr 4 three-argument API, converting the nanosecond devicetree value to the microsecond spi_cs_control delay field.
