Counter frequency for generic timer of Arm-A53 based Application
Processing Unit(APU) is not configuring in case if First Stage Boot
Loader(FSBL) does not initialize counter frequency. This happens
when FSBL is running from Arm-R5 based Real-time Processing Unit(RPU).
Because of that generic timer driver functionality is not working.
So configure counter frequency during initialization.

This patch adds LPD WDT clock node to the pm_clock clocks structure list
so that LPD WDT can be used from Linux.

Also this patch removes the CLK_LPD_LSBUS from invalid clock list to
allow the registration of this clock to CCF framework as it is the
parent of LPD WDT.

Enforce full include path for includes. Deprecate old paths.

The following folders inside include/lib have been left unchanged:

- include/lib/cpus/${ARCH}
- include/lib/el3_runtime/${ARCH}

The reason for this change is that having a global namespace for
includes isn't a good idea. It defeats one of the advantages of having
folders and it introduces problems that are sometimes subtle (because
you may not know the header you are actually including if there are two
of them).

For example, this patch had to be created because two headers were
called the same way: e0ea0928 ("Fix gpio includes of mt8173 platform
to avoid collision."). More recently, this patch has had similar
problems: 46f9b2c3 ("drivers: add tzc380 support").

This problem was introduced in commit 4ecca339

 ("Move include and
source files to logical locations"). At that time, there weren't too
many headers so it wasn't a real issue. However, time has shown that
this creates problems.

Platforms that want to preserve the way they include headers may add the
removed paths to PLAT_INCLUDES, but this is discouraged.

All identifiers, regardless of use, that start with two underscores are
reserved. This means they can't be used in header guards.

The style that this project is now to use the full name of the file in
capital letters followed by 'H'. For example, for a file called
"uart_example.h", the header guard is UART_EXAMPLE_H.

The exceptions are files that are imported from other projects:

- CryptoCell driver
- dt-bindings folders
- zlib headers

To make ULPI transceiver work, a HIGH - LOW - HIGH pulse needs
to be given to resetb pin of ULPI chip. In ZYNQMP, this resetb
pin is being driven by BOOT MODE PIN 1. The BOOT MODE PIN's
are controlled by BOOT_PIN_CTRL register present in CRL_APB
address region. Since CRL_APB can be resticted to secure access,
this pin should be controlled by ATF.
