sunxi/nand: Add support to the SPL for loading u-boot from internal NAND memory
This commit adds support to the sunxi SPL to load u-boot from the internal
NAND. Note this only adds support to access the boot partitions to load
u-boot, full NAND support to load the kernel, etc. from the nand data
partition will come later.

usb: kbd: Fix key repeat not always working
The usb-kbd key repeat code assumes that reports get repeated every 40 ms,
this is never true when using CONFIG_SYS_USB_EVENT_POLL_VIA_CONTROL_EP, and
does not always works for CONFIG_SYS_USB_EVENT_POLL and
CONFIG_SYS_USB_EVENT_POLL_VIA_INT_QUEUE since not all usb keyboards honor
the usb_set_idle() command.
For CONFIG_SYS_USB_EVENT_POLL we must use usb_set_idle() since we do a
blocking wait for the hid report, so if we do not tell the keyboard to send
a hid report every 40ms even if nothing changes then we will block u-boot
for 1s (the default u-boot usb interrupt packet timeout). Note that in this
case on keyboards which do not support usb_set_idle() we loose and we actually
get 1s latencies on other u-boot activities.
For the other poll-methods this commit stops using usb_set_idle() and instead
repeats the last received hid-report every 40 ms as long as no new hid-report
is received. This fixes key-repeat not working at all with
CONFIG_SYS_USB_EVENT_POLL_VIA_CONTROL_EP and fixes it not working with
keyboards which do not implement usb_set_idle() when using
CONFIG_SYS_USB_EVENT_POLL_VIA_INT_QUEUE.
