at91sam7: ensure probed flash bank has a name (fix a segfault)

Before this commit, openocd used to segfault when probing flash
of an at91sam7x512 (which contains 2 banks of flash). This was due
to the way it systematically insert a new flash bank without setting
its name.
Then, when get_flash_bank_by_name_noprobe() is called, it is doing
a strcmp() on the non-initialized bank->name.

This commit prevents allocation of second probed bank if it is already
allocated (for example, if it is set in a target config file). If a
new bank really needs to be allocated, it ensures that a default name
is set.

target: make it absolutely clear that no null pointers are accepted

there are no comments about what the rules w.r.t. null pointers
are and it is inconsistent.

It's simply a bug in the app if we ask about the properties of a null
pointer w.r.t. what kind of target it is. It's equally wrong to say
that it is an arm target as that it isn't an arm target.

ft2232: Set PWR_RST and LOOPBACK for xds100v2

The CPLD on the xds100v2 expects to see a rising edge on PWR_RST to
enable the outputs.  This patch creates that transition correctly by
fixing the direction register for PWR_RST.

THe CPLD will also loop back the data if the LOOPBACK signal is
asserted.  Set this signal to an output and keep it clear.

This was tested with a TI DM3730 Beagleboard xM.
