dm: Split the simple malloc() implementation into its own file

The simple malloc() implementation is used when memory is tight. It provides
a simple buffer with an incrementing pointer.

At present the implementation is inside dlmalloc. Move it into its own file
so that it is easier to find.

Rather than using relocation as a signal that the full malloc() is
available, add a special GD_FLG_FULL_MALLOC_INIT flag. This signals that the
simple malloc() should no longer be used.

In some cases, such as SPL, even the code space used by the full malloc() is
wasteful. Add a CONFIG_SYS_MALLOC_SIMPLE option to provide only the simple
malloc. In this case the full malloc is not available at all. It saves about
1KB of code space and about 0.5KB of data on Thumb 2.

dm: gpio: Add a function to read an ID from a list of GPIOs

For board IDs a common approach is to set aside several GPIOs for use in
determining the board ID. This can provide information about board features
and the revision.

Add a function that turns a list of GPIOs into an integer by assigning
each GPIO to a single bit.

dm: serial: Move current serial port pointer to global_data

In general we can't store things in the data section until we have inited
SDRAM. Some platforms allow this (e.g. those with SPL) but some don't. Move
the pointer to global_data so that it will work on all platforms.

Without this fix the serial port will not work prior to relocation with
driver model on some platforms.

ppc: Zap Hymod board

Remove this board as this is the only one last user of eeprom_probe(),
which is pretty non-standard stuff.

This patch also removes all the PHP, SQL and CSS stuff from U-Boot,
which probably makes U-Boot a bit less IoT ;-)

dm: gpio: Implement GPIO reservation in the uclass

We have several GPIO drivers now and all are doing similar things to record
which GPIOs are reserved.

Move this logic into the uclass to make the drivers similar.

We retain the request()/free() methods since currently one driver does use
these for setting up the pin.
