crosstyan d8db9e1eb0 fix(llcc68): move SPI CS delay to devicetree
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.

Semtech LLCC68 radio transceiver used with the Weihua application driver.
This compatible intentionally differs from Zephyr's upstream
semtech,llcc68 binding so the application-owned driver can coexist
with Zephyr releases that ship a native LLCC68 binding and driver.
compatible: "semtech,llcc68-weihua"

properties:
reset-gpios:
type: phandle-array

GPIO connected to the modem's NRESET signal.
This signal is open-drain, active-low as interpreted by the
modem.

GPIO connected to DIO1. This GPIO will be used as a generic
IRQ line from the chip.
