payload/ubootcli: add the u-boot cli

Browse source 
This is a first cut at the u-boot cli. It builds and loads and runs
and has no commands. That's next.

Interestingly, this is code right from our u-boot tree, and it's full
of style violations which I don't intend to fix.

Remove dependency on anything else, but this won't work until the
libpayload serial drivers for arm are set up.

BUG=None
TEST=build and boot on nyan and get a u-boot cli prompt.
BRANCH=None

/**
* A linker list is constructed by grouping together linker input
* sections, each containning one entry of the list. Each input section
* contains a constant initialized variable which holds the entry's
* content. Linker list input sections are constructed from the list
* and entry names, plus a prefix which allows grouping all lists
* together. Assuming _list and _entry are the list and entry names,
* then the corresponding input section name is
*
* _u_boot_list + _2_ + @_list + _2_ + @_entry
*
* and the C variable name is
*
* .u_boot_list_ + 2_ + @_list + _2_ + @_entry
*
* This ensures uniqueness for both input section and C variable name.
*
* Note that the names differ only in the first character, "." for the
* setion and "_" for the variable, so that the linker cannot confuse
* section and symbol names. From now on, both names will be referred
* to as
*
* %u_boot_list_ + 2_ + @_list + _2_ + @_entry
*
* Entry variables need never be referred to directly.
*
* The naming scheme for input sections allows grouping all linker lists
* into a single linker output section and grouping all entries for a
* single list.
*
* Note the two '_2_' constant components in the names: their presence
* allows putting a start and end symbols around a list, by mapping
* these symbols to sections names with components "1" (before) and
* "3" (after) instead of "2" (within).
* Start and end symbols for a list can generally be defined as
*
* %u_boot_list_2_ + @_list + _1_...
* %u_boot_list_2_ + @_list + _3_...
*
* Start and end symbols for the whole of the linker lists area can be
* defined as
*
* %u_boot_list_1_...
* %u_boot_list_3_...
*
* Here is an example of the sorted sections which result from a list
* "array" made up of three entries : "first", "second" and "third",
* iterated at least once.
*
* .u_boot_list_2_array_1
* .u_boot_list_2_array_2_first
* .u_boot_list_2_array_2_second
* .u_boot_list_2_array_2_third
* .u_boot_list_2_array_3
*
* If lists must be divided into sublists (e.g. for iterating only on
* part of a list), one can simply give the list a name of the form
* 'outer_2_inner', where 'outer' is the global list name and 'inner'
* is the sub-list name. Iterators for the whole list should use the
* global list name ("outer"); iterators for only a sub-list should use
* the full sub-list name ("outer_2_inner").
*
* Here is an example of the sections generated from a global list
* named "drivers", two sub-lists named "i2c" and "pci", and iterators
* defined for the whole list and each sub-list:
*
* %u_boot_list_2_drivers_1
* %u_boot_list_2_drivers_2_i2c_1
* %u_boot_list_2_drivers_2_i2c_2_first
* %u_boot_list_2_drivers_2_i2c_2_first
* %u_boot_list_2_drivers_2_i2c_2_second
* %u_boot_list_2_drivers_2_i2c_2_third
* %u_boot_list_2_drivers_2_i2c_3
* %u_boot_list_2_drivers_2_pci_1
* %u_boot_list_2_drivers_2_pci_2_first
* %u_boot_list_2_drivers_2_pci_2_second
