[PATCH v3 1/4] mkimage: add a flag to describe whether -A is specified

[Samuel Holland]

From: Icenowy Zheng <icenowy at aosc.io>

The sunxi_egon type used to take no -A argument (because we assume sunxi
targets are all ARM). However, as Allwinner D1 appears as the first
RISC-V sunxi target, we need to support -A; in addition, as external
projects rely on U-Boot mkimage to generate sunxi eGON.BT0 header, we
need to keep compatibility with command line without -A.

As the default value of arch in mkimage is not proper (IH_ARCH_PPC
instead of IH_ARCH_INVALID), to keep more compatibility, add an Aflag
field to image parameters to describe whether an architecture is
explicitly specified.
