[ Upstream commit 5c782817a981981917ec3c647cf521022ee07143 ] In some cases when firmware is busy or updating, some mailbox commands still timeout on some newer CPUs. To fix this issue, change how we process timeout. With this change, replaced timeout from using simple count with real timeout in micro-seconds using ktime. When the command response takes more than average processing time, yield to other tasks. The worst case timeout is extended upto 1 milli-second.
