description:
sun4v: Change clk and sclk variables to unsigned type so modern faster systems with CPU frequencies above 2 Ghz are shown correctly. Example is a 3599.910 MHz SPARC T5-2 system that otherwise is 
shown incorrectly as -695.-57 MHz. Based on code from OpenBSD cpu.c rev. 1.41. Verified on sun4u using qemu and sun4v on SPARC T5-2
