zephyr: Fix the CONFIG_CPU_PROCHOT_ACTIVE_LOW option
zephyr: Fix the CONFIG_CPU_PROCHOT_ACTIVE_LOW option

The KConfig option CONFIG_PLATFORM_EC_POWERSEQ_CPU_PROCHOT_ACTIVE_LOW
was not enabling the correct platform/ec option
CONFIG_CPU_PROCHOT_ACTIVE_LOW.

This greatly speeds up booting the kernel on Zephyr builds as the EC was
previously always asserting PROCHOT to the AP.
