isspace() and strim() are not in the typical user-mode string.h, so
put them in a separate compilation unit so that they can be built into
tools that need them independent of the other common string functions.
This allows code shared by u-boot and the linux user-mode tools to link.

This is used to obtain information about the panel such as its
resolution and type.
This is a tidied-up version of the original code pulled from
https://github.com/ynezz/u-boot-edid.
The changes we made are:
- removed bit fields in the struct;
- removed endianness cases in the struct;
- fixed some wrong definitions;
- fixed to fit 80 columns;
- fixed some code styles.

This new command supports hashing SHA1 and SHA256. It could be extended
to others such as MD5 and the CRC algorithms. The syntax is modeled on
those:
hash <algorithm> <address> <length> [*<dest_addr> | <dest_envvar>]
to calculate a hash, and:
hash -v <algorithm> <address> <length> [*<verify_addr> | <verify_envvar>]
to verify a hash.
Use CONFIG_CMD_HASH to enable the command, CONFIG_SHA1 to enable SHA1 and
CONFIG_SHA256 to enable SHA256.
The existing sha1sum command remains.

In the newer versions of designware i2c IP there is the possibility
of configuring it with IC_EMPTYFIFO_HOLD_MASTER_EN=1, which basically
requires the s/w to generate the stop bit condition directly, as
the h/w will not automatically generate it when TX_FIFO is empty.
To avoid generation of an extra 0x0 byte sent as data, the
IC_STOP command must be sent along with the last IC_CMD.
This patch always writes bit[9] of ic_data_cmd even in the
older versions, assuming that it is a noop there.

The I2C block reset configures the I2C bus speed to strange value.
Read the I2C speed from the block before reseting the block and
restore it afterwards, so the I2C operates correctly. This issue
can be replicated by doing unsuccessful I2C transfer, after such
transfer finishes, the I2C block clock speed is misconfigured.
