[PATCH] arm64/hw_breakpoint: Determine lengths from generic perf breakpoint macros

[Anshuman Khandual]

Both platform i.e ARM_BREAKPOINT_LEN_X and generic i.e HW_BREAKPOINT_LEN_X
macros are used interchangeably to convert event->attr.bp_len and platform
breakpoint control arch_hw_breakpoint_ctrl->len. Let's be consistent while
deriving one from the other. This does not cause any functional changes.
