2b1be55819 scsi: scsi_transport_fc: refactor event posting routines
There are two routines generating transport events that do the same thing
with only a couple of values set differently.

Refactor so there's a single routine doing the netlink operations to send
the event. All the differences are passed as arguments. Export the symbol
so the generic routine can be called by llds.

Modify the existing two event routines to use the helper.

94e424c6b6 scsi: ufs: Remove "<name>-fixed-regulator" device tree property
"<name>-fixed-regulator" device tree property can be safely removed because
below things are fixed or resolved,

1. "<name>-max-microamp" becomes optional property: Undefined
   "<name>-max-microamp" will not cause initialization fail if
   "<name>-fixed-regulator" is not defined.

2. Current switching operation (by regulator_set_load) now has rules:
   Regulators will have undefined current limit if "<name>-fixed-regulator"
   is not defined. But this is safe because only regulator which has
   configured current limit from "<name>-max-microamp" property is allowed
   to change its load.

Although "<name>-fixed-regulator" is not used in any dt-bindings in tree,
this patch is still safe for regulators already defined
"<name>-fixed-regulator". To be more clear, if a regulator defined
"<name>-fixed-regulator" before, the behavior difference after this patch
is,

1. "<name>-max-microamp":
   If a regulator defined "<name>-fixed-regulator", it is not necessary
   to define "<name>-max-microamp" property in device tree and it is
   expected to have an undefined current limit, i.e., "max_uA" field
   is zero in struct ufs_vreg. This is exactly the same as patched.

2. "vcc-supply-1p8" or volatge range settings:
   * For vcc, vccq or vccq2, these three regulators shall not define
     "<name>-fixed-regulator" because defining it will lead to
     undefined voltage range and thus voltage switching will be
     unexpected.
   * For other regulators with undefined voltage range, voltage range
     will be still undefined after patched.

Therefore this patch is safe for all existed regulators with
"<name>-fixed-regulator" property already defined.
