Daniel Leung 2e7831562a samples: mec15xxevb_assy6853/pm: shorten wait after deep sleep
The origin for sleeping for 3ms after coming out of deep sleep
was to wait for PLL to lock so that UART would not send
garbage characters due to incorrect clock. In the deep sleep
code, it spins to wait for the PLL to lock so there is no need
to wait for 3ms in the app. So shorten it like other busy wait.

The Zephyr Project is a scalable real-time operating system (RTOS) supporting
multiple hardware architectures, optimized for resource constrained devices,
and built with security in mind.

The Zephyr OS is based on a small-footprint kernel designed for use on
resource-constrained systems: from simple embedded environmental sensors and
LED wearables to sophisticated smart watches and IoT wireless gateways.

The Zephyr kernel supports multiple architectures, including ARM Cortex-M,
Intel x86, ARC, Nios II, Tensilica Xtensa, and RISC-V, and a large number of
`supported boards`_.
