Jo-Philipp Wich 7a58972680 uboot-sunxi: fix default config for OLIMEX A13 SOM (FS#239)
The current uboot default config for the A13 SOM erroneously enables support
for the AXP209 power regulator IC which is not present on the board.

This superfluous support module sets an incorrect initial clock frequency and
confuses the kernel, ultimately leading to a boot failure later on.

Properly disable the PMIC support and enable the EHCI support by translating
the deprecated SYS_EXTRA_OPTIONS values into proper SUNXI_NO_PMIC and
USB_EHCI_HCD symbols respectively.

Also rename 002-add-olimex-a13-som.diff to 002-add-olimex-a13-som.patch and
refresh the remaining patches of the series while we're at it.
