Canokey core currently using 16 bytes as maximum packet size for

maximum packet size is required according to USB 2.0 specification.
Since we don't acutally need to run the device in high-speed, simply

This commit wires up bootinfo's RNG seed attribute so that Linux VMs can
have their RNG seeded from the earliest possible time in boot, just like
the "rng-seed" device tree property on those platforms. The link
contains the corresponding Linux patch.

Introduce the third method GLOBAL_DIRTY_LIMIT of dirty
tracking for calculate dirtyrate periodly for dirty page
rate limit.
Add dirtylimit.c to implement dirtyrate calculation periodly,
which will be used for dirty page rate limit.
