-USB Ehci emulation supports host controller capability registers.
-But its mmio '.write' function was missing, which lead to a null
-pointer dereference issue. Add a do nothing 'ehci_caps_write'
-definition to avoid it; Do nothing because capability registers

-Subject: [PATCH] rng: add request queue support to rng-random
-
-Requests are now created in the RngBackend parent class and the
-code path is shared by both rng-egd and rng-random.
-
-This commit fixes the rng-random implementation which processed
-only one request at a time and simply discarded all but the most
-recent one. In the guest this manifested as delayed completion
-of reads from virtio-rng, i.e. a read was completed only after
-another read was issued.
-
-By switching rng-random to use the same request queue as rng-egd,
-the unsafe stack-based allocation of the entropy buffer is
-eliminated and replaced with g_malloc.
