timer: dw-apb: Add missing 64bit up-conversion
The generic timer count is an incrementing 64bit value and a timer driver
must return an incrementing 64bit value. The DW APB timer only provides a
32bit timer counting down, thus the result must be inverted and converted
to a 64bit value. The current implementation is however missing the 64bit
up-conversion and this results in random timer roll-overs, which in turn
triggers random timeouts throughout the codebase.
This patch adds the missing 64bit up-conversion to fix the issue.
