There are a number of proc_gen branches removed that are trivially
dead code and comments that refer to P7. As well as those:
- Oliver points out that add_xics_icps() must be unused on POWER8
because it asserts if number of threads > 4, so remove it.
- Change 16b7ae641 ("Remove POWER7 and POWER7+ support") removed all
references to opal_boot_trampoline, so remove that.
- It also removed the only non-trival choose_bus implementation, so
that is removed and its caller simplified.
- Remove the paca code, later CPUs use pcia.

This changes to build system to use thin archives rather than
incremental linking for built-in.o, similar to recent change to Linux.
built-in.o is renamed to built-in.a, and is created as a thin archive
with no index, for speed and size. All built-in.a are aggregated into
a skiboot.tmp.a which is a thin archive built with an index, making it
suitable or linking. This is input into the final link.
The advantags of build size and linker code placement flexibility are
not as great with skiboot as a bigger project like Linux, but it's a
conceptually better way to build, and is more compatible with link
time optimisation in toolchains which might be interesting for skiboot
particularly for size reductions.
Size of build tree before this patch is 34.4MB, afterwards 23.1MB.

This parses the firmware event log information from the
secureboot_tpm_info HDAT structure and add it to the tpm device tree
node.
There can be multiple secureboot_tpm_info entries with each entry
corresponding to a master processor that has a tpm device, however,
multiple tpm is not supported.

Adds basic parsing for i2c devices that are attached to the processor
I2C interfaces. This is mainly VPD SEEPROMs.
