uart: Don't change settings or throttle putc for Hyper-V
Azure setup does not like it when FreeBSD overrides the settings of the
UART device. When Hyper-V is detected, don't do this and also don't
throttle putc() output. This is a workaround for the early boot hang
of FreeBSD on Azure.
Tested on Azure, ESXi (VM with serial port), and SG-8200
