  When just including <asm/arm_pmuv3.h>:

    arch/arm/include/asm/arm_pmuv3.h:110:13: error: ‘write_pmevtypern’ defined but not used [-Werror=unused-function]
      110 | static void write_pmevtypern(int n, unsigned long val)
	  |             ^~~~~~~~~~~~~~~~
    arch/arm/include/asm/arm_pmuv3.h:103:13: error: ‘write_pmevcntrn’ defined but not used [-Werror=unused-function]
      103 | static void write_pmevcntrn(int n, unsigned long val)
	  |             ^~~~~~~~~~~~~~~
    arch/arm/include/asm/arm_pmuv3.h:95:22: error: ‘read_pmevcntrn’ defined but not used [-Werror=unused-function]
       95 | static unsigned long read_pmevcntrn(int n)
	  |                      ^~~~~~~~~~~~~~

Fix this by adding the missing "inline" keywords to the three accessor
functions that lack them.

Fixes: 009d6dc87a568db6 ("ARM: perf: Allow the use of the PMUv3 driver on 32bit ARM")
