This patch reads the chipid registers directly instead of making
pm call when running at BL32. User should ensure that these registers
should always be accessed from APU in their system configuration.

The vcu disable bit in efuse ipdisable register is valid
only if PL powered up so, consider PL powerup status for
determing EG/EV part. If PL is not powered up, display
EG/EV as a part of string. The PL powerup status will
be filled by pmufw based on PL PROGB status in the
9th bit of version field.This patch also used IPI
to get this info from pmufw instead of directly accessing
the registers. Accessing this info from pmufw using
IPI fixes the issue of PMUFW access denied error for
reading IPDISABLE register.

Xilinx now requires the PMU FW when using ATF, so it doesn't make sense
to maintain checks for the PMU FW in ATF. This also means that cases
where ATF came up before the PMU FW (such as on QEMU) ATF will now hang
waiting for the PMU FW instead of aborting.

Read ipdisable reg which needs to be used for cg/eg/ev device detection.
ATF runs in EL3 that's why this read can be done directly.

This patch moves the definition for `plat_get_syscnt_freq()`
from arm_bl31_setup.c to arm_common.c. This could be useful
in case a delay timer needs to be installed based on the
generic timer in other BLs.
This patch also modifies the return type for this function
from `uint64_t` to `unsigned long long` within ARM and other
platform files.
