[ Upstream commit ca374f5d92b8ae778f6a37dd3e7ed809bbf7a953 ]

All fields of the SASProtocolTimerConfig structure have the __le32 type.
As such, use cpu_to_le32() to initialize them. This change suppresses many
sparse warnings:

warning: incorrect type in assignment (different base types)
expected restricted __le32 [addressable] [usertype] pageCode
got int

Note that the check to limit the value of the STP_IDLE_TMO field is removed
as this field is initialized using the fixed (and small) value defined by
the STP_IDLE_TIME macro.

The pm8001_dbg() calls printing the values of the SASProtocolTimerConfig
structure fileds are changed to use le32_to_cpu() to present the values in
human readable form.
