Android Header v3 and vendor boot partition are introduced
from Android-11(R).
Header populate:
Header v3 is no longer compatible with v0/1/2 header, we
add populate_andr_img_hdr() to merge boot and vendor_boot
partition header into struct andr_img_hdr in order to
compatible with v0/1/2 header.
resource.img:
The second_addr and second_size fields are removed in v3,
so we require resource partition to restore resource.img.
A/B system:
If not A/B system, the boot.img header version is 3 and
recovery header is version 2.
AVB load image:
- If allow verification error: the image is loaded by
ops->get_preloaded_partition() which auto populates
boot_img_hdr_v3.
- If not allow verification error: the image is full loaded
by ops->read_from_partition() which doesn't populate
boot_img_hdr_v3, we need to fix it.

Rockchip platforms defines BCB message at the 16KB offset of
misc partition while the Google defines it at 0x0 offset.
From Android-Q, the 0x0 offset is mandary on Google VTS, so this
patch is a compatibility according to android image 'os_version'.
Android os version >= 10 is at 0x0 offset, otherwise at 16KB offset.

We provide a "logo" partition for user to store logo.bmp
and update from kernel user space dynamically.
This patch follows the rkdevelop usage:
- Only support store one picture named "logo.bmp";
- Use "dd" command to generate partition image with logo.img
eg: "dd if=logo.bmp of=logo.img count=1 bs=19456"

We should parse node name to identify the gpio port before
reading base address, it avoids to use miss match address.
Move out gpio_parse_base_address() from sub string parse is
better.
Set gpio as input mode before reading.
