To read 64bit time in 32 bit we have to read lower & upper half
separately and 'or' them together. However, upper half time may
have changed by the time we read lower half. Thus, the resultant
64 bit time may not be accurate.
Consider lower half time value only if upper half time value has
not changed.

OpenSBI manages outstanding TLB flush requests by queueing
them in a fifo synchronously. An ipi sync which uses an
atomic operation on MMIO address is no longer required.
Remove the ipi sync method from platform header and all usage.

The drivers and libfdt are built as libsbiutils.a
instead of libplatsbi.a.
libsbiutils.a are not built per platform specific. Thus,
enable all drivers by default.

Currently, platform/common contains platform/non-platform specific
common minimal drivers and libraries. This is helpful is all platforms
are built within opensbi framework.
Move them to lib/utils so that any external platform code also can
reuse the minimalistic drivers or other common libraries.
This patch doesn't introduce any functional changes.
