Add the ops for GPIO driver set_dir_flags() to set the dir flags.
The user can update the direction and configuration
of each GPIO with a only call to dm_gpio_set_dir_flags() or
dm_gpio_set_dir() and respecting the configuration provided by
device tree (saved in desc->flags).
When these optional ops are absent, the gpio uclass use the mandatory
ops (direction_output, direction_input, get_value) and desc->flags
to manage only the main dir flags:
- GPIOD_IS_IN
- GPIOD_IS_OUT
- GPIOD_IS_OUT_ACTIVE
- GPIOD_ACTIVE_LOW

This commit manages the new dir flags that can be used in gpio
specifiers to indicate the pull-up or pull-down resistor
configuration for output gpio (GPIO_PULL_UP, GPIO_PULL_DOWN)
or the Open Drain/Open Source configuration for input gpio
(GPIO_OPEN_DRAIN, GPIO_OPEN_SOURCE).
These flags are already supported in Linux kernel in gpio lib.
This patch only parse and save the direction flags in GPIO
descriptor (desc->flags), it prepares the introduction of new ops
to manage them.
The GPIO uclass supports new GPIO flags from device-tree
(GPIO_XXX define in include/dt-bindings/gpio/gpio.h)
and translate them in the dir flags (GPIOD_XXX):
- GPIO_PULL_UP => GPIOD_PULL_UP
- GPIO_PULL_DOWN => GPIOD_PULL_DOWN
- GPIO_OPEN_DRAIN => GPIOD_OPEN_DRAIN
- GPIO_OPEN_SOURCE => GPIOD_OPEN_SOURCE

For certain btrfs files with compressed file extent, uboot will fail to
load it:
btrfs_read_extent_reg: disk_bytenr=14229504 disk_len=73728 offset=0 nr_bytes=131
072
decompress_lzo: tot_len=70770
decompress_lzo: in_len=1389
decompress_lzo: in_len=2400
decompress_lzo: in_len=3002
decompress_lzo: in_len=1379
decompress_lzo: in_len=88539136
decompress_lzo: header error, in_len=88539136 clen=65534 tot_len=62580
NOTE: except the last line, all other lines are debug output.
Btrfs lzo compression uses its own format to record compressed size
(segment header, LE32).
However to make decompression easier, we never put such segment header
across page boundary.
In above case, the xxd dump of the lzo compressed data looks like this:
00001fe0: 4cdc 02fc 0bfd 02c0 dc02 0d13 0100 0001 L...............
00001ff0: 0000 0008 0300 0000 0000 0011 0000|0000 ................
00002000: 4705 0000 0001 cc02 0000 0000 0000 1e01 G...............
'|' is the "expected" segment header start position.
But in that page, there are only 2 bytes left, can't contain the 4 bytes
segment header.
So btrfs compression will skip that 2 bytes, put the segment header in
next page directly.
Uboot doesn't have such check, and read the header with 2 bytes offset,
result 0x05470000 (88539136), other than the expected result
0x00000547 (1351), resulting above error.
Follow the btrfs-progs restore implementation, by introducing tot_in to
record total processed bytes (including headers), and do proper page
boundary skip to fix it.
Please note that, current code base doesn't parse fs_info thus we can't
grab sector size easily, so it uses PAGE_SIZE, and relying on fs open
time check to exclude unsupported sector size.

Although in theory u-boot fs driver could easily support more sector
sizes, current code base doesn't have good enough way to grab sector
size yet.
This would cause problem for later LZO fixes which rely on sector size.
And considering that most u-boot boards are using 4K page size, which is
also the most common sector size for btrfs, rejecting fs with
non-page-sized sector size shouldn't cause much problem.
This should only be a quick fix before we implement better sector size
support.

At present a device can read its ofdata before its parent has done the

property, thus affecting the operation of dev_read_addr(), for example.
We already probe parent devices before children so it does not seem to be
