cpukit/arm: Correct register definition
The register definition for the CP15 PMCR (performance monitor control register) has the bits for X (export enable) and D (clock divider enable) backwards. Correct them according to ARMv7-A/R Architecture Reference Manual, Rev C, Section B4.1.117. Consequences: On an implementation that starts off with D set at reset, the clock divider will not be disabled by using RTEMS' definition of the D bit. Tested by using the counter on Xilinx Zynq 7020 to measure some atomic accesses and cache flushing operations.
