This augments the core machine code for the Integrator platforms

Keystone SOC doesn't have depedency to enable clocks in early

5523e4092e ARM: OMAP5/DRA7: realtime_counter: Configure CNTFRQ register
The realtime counter called master counter, produces the count
used by the private timer peripherals in the MPU_CLUSTER. The
CNTFRQ per cpu register is used to denote the frequency of the counter.
Currently the frequency value is passed from the
DT file, but this is not scalable when we have other non-DT guest
OS. This register must be set to the right value by the
secure rom code. Setting this register helps in propagating the right
frequency value across OSes.

More discussions and the reason for adding this in a non-DT
way can be seen from below.
http://www.mail-archive.com/linux-omap@vger.kernel.org/msg93832.html

So configuring this secure register for all the cpus here.

6423d6df14 ARM: OMAP2+: hwmod: check for module address space during init
The hwmod init sequence involves initializing and idling all the
hwmods during bootup. If a module class has sysconfig, the init
sequence utilizes the module register base for performing any
sysc configuration.

The module address space is being removed from hwmod database and
retrieved from the <reg> property of the corresponding DT node.
If a hwmod does not have its corresponding DT node defined and the
memory address space is not defined in the corresponding
omap_hwmod_ocp_if, then the module register target address space
would be NULL and any sysc programming would result in a NULL
pointer dereference and a kernel boot hang.

Handle this scenario by checking for a valid module address space
during the _init of each hwmod, and leaving it in the registered
state if no module register address base is defined in either of
the hwmod data or the DT data.

OMAP5 ES1.0 was intended as a test chip and has major register level
differences w.r.t ES2.0 revision of the chip. All register defines,
dts support has been solely added for ES2.0 version of the chip.
Further, all ES1.0 chips and platforms are supposed to have been
removed from circulation. Hence, there is no need to further retain
any resemblence of ES1.0 support in id detection code.

Remove the omap_revision handling and BUG() instead to prevent folks
who mistakenly try an older unsupported chip and report bogus errors.

The real time counter also called master counter, is a free-running
counter. It produces the count used by the CPU local timer peripherals
in the MPU cluster. The timer counts at a rate of 6.144 MHz.

The ratio registers are missing for a sys-clk of 20MHZ which is used
by DRA7 socs. So because of this, the counter was getting wrongly
programmed for a sys-clk of 38.4Mhz(default). So adding the ratio
registers for 20MHZ sys-clk.
