pieeprom-2021-06-11 - Add USB_MSD_STARTUP_DELAY

* Minor update to BRCM SDRAM settings. * Add USB_MSD_STARTUP_DELAY option (default 0 option). This adds a configurable delay (in milliseconds) the first time the USB host controller is initialised before device enumeration. Normally, this should not be required. However, some HDD enclosures may require an extended startup delay in order to spinup drives. Without this the get-capacity command may stall and timeout.
