ice: use read_poll_timeout_atomic in ice_read_phy_tstamp_ll_e810
The ice_read_phy_tstamp_ll_e810 function repeatedly reads the PF_SB_ATQBAL
register until the TS_LL_READ_TS bit is cleared. This is a perfect
candidate for using rd32_poll_timeout. However, the default implementation
uses a sleep-based wait. Use read_poll_timeout_atomic macro which is based
on the non-sleeping implementation and use it to replace the loop reading
in the ice_read_phy_tstamp_ll_e810 function.
