Implement ms timer and fix all timers

Browse Source 
This will fix everything that uses a timer (or sleep).

Without this any function like eMMC/SD read/write/verify, TSEC/SE, etc can break when the time reaches the max value of the u32 microsecond timer (71minutes).

This fixes every possible breakage, including backup and restore (read/write/verify errors) that takes a lot of time.

The new max before a timer reset is now 48 days (the old one was 71 minutes)
