ARM: am33xx: Fix DDR initialization delays

The current delays in the DDR initialization routines for am33xx
architectures are sometimes not running long enough leading to DDR
init errors. On am437x, this shows up as an L3 NOC error after the
kernel boots. This is due to the timer not being initialized
properly, but instead still containing the timer init values from
the boot ROM which cause timers to expire in 1/4th the time
required.

timer_init is typically not called until board_init_r, however on
am33xx/am43xx udelay is required in sdram_init which is called
from board_init_f, so a call to timer_init is required earlier.

Note that this issue introduced in v2015.01 by:

b352dde "am33xx: Drop timer_init call from s_init".

Although this could instead fixed by reverting said commit, it
would cause timer_init to be called twice in both SPL and non-SPL
cases. This gives a little more fine grained control and also
matches what is being done on omap-command and fsl-layerscape.

Stephen Warren [Thu, 28 Apr 2016 18:45:44 +0000 (12:45 -0600)]
ARM: fix ifdefs in ARMv8 lowlevel_init()

Commit 724219a65f55 "ARM: always perform per-CPU GIC init" removed some
ifdefs to unify the MULTIENTRY-vs-non-MULTIENTRY paths. However, the
wrong endif was removed. This patch adds back that missing endif, and
adds a new ifdef to match the endif the now-correctly-terminated block
used to match against. Use "git show -U25 724219a65f55" to see enough
context to make the original issue clear.

In practical terms, this makes no difference to runtime behaviour. The
code that was incorrectly compiled into the binary when ifndef MULTIENTRY
is a no-op for other cases, since branch_if_master evaluates to a hard-
coded jump. The only issues were:

- A few extra instructions were added to the binary.
- The comment on the endif at the very end of the function, indicating
which ifdef it matched, were wrong.

An alternative might be to simply fix the comment on that trailing ifdef,
but that only addresses the second point above, not the first.

pci: tegra: fix DM conversion issues on Tegra20

Tegra20's PCIe controller has a couple of quirks. There are workarounds in
the driver for these, but they don't work after the DM conversion:

1) The PCI_CLASS value is wrong in HW.

This is worked around in pci_tegra_read_config() by patching up the value
read from that register. Pre-DM, the PCIe core always read this via a
16-bit access to the 16-bit offset 0xa. With DM, 32-bit accesses are used,
so we need to check for offset 0x8 instead. Mask the offset value back to
32-bit alignment to make this work in all cases.

2) Accessing devices other than dev 1 causes a data abort.

Pre-DM, this was worked around in pci_skip_dev(), which the PCIe core code
called during enumeration while iterating over a bus. The DM PCIe core
doesn't use this function. Instead, enhance tegra_pcie_conf_address() to
validate the bdf being accessed, and refuse to access invalid devices.
Since pci_skip_dev() isn't used, delete it.

I've also validated that both these WARs are only needed for Tegra20, by
testing on Tegra30/Cardhu and Tegra124/Jetson TKx. So, compile them in
conditionally.

In current Linux kernel Tegra DT files, 64-bit addresses are represented
