mb/google/var/fatcat/lapis: adjust 'cirrus,detect-us' property to

improve the noise situation

When a 3.5 mm headset is connected, noise occurs during system startup
or wake-up from suspend.Setting this value "detect-us" lower should
improve the noise situation, therefore, we adjust detect_us to 100us.

BUG=b/454450799
TEST=cat /sys/kernel/debug/regmap/<sdw_dev>/registers | grep 010040
to ensure the changes take effect and improve the noise situation.
