robert-hh 9d2e179fa5 mimxrt: Fix CPU freeze when calling __WFE() in MICROPY_EVENT_POLL_HOOK. 
This issue affected i.MX RT 1052, 1062 and 1064.  It seems to be addressed
by Errata ERR006223, which also mentions i.MX RT101x and 102x, but these
devices worked well even without the change.  As a side effect, the current
consumption at an idle REPL drops significantly with this fix.

Fixes issue #7235.
