crypto: x86 - remove SHA multibuffer routines and mcryptd 

mainline inclusion
from mainline-v4.20-rc1
commit ab8085c130edd65be0d95cc95c28b51c4c6faf9d
category: bugfix
bugzilla: NA
CVE: NA

-----------------------------------------------

As it turns out, the AVX2 multibuffer SHA routines are currently
broken [0], in a way that would have likely been noticed if this
code were in wide use. Since the code is too complicated to be
maintained by anyone except the original authors, and since the
performance benefits for real-world use cases are debatable to
begin with, it is better to drop it entirely for the moment.

#
# RES_* macros take a name, a count and an optional alignment.
# The count in in terms of the base size of the macro, and the
# default alignment is the base size.
# The macros are:
# Macro Base size
# RES_B 1
# RES_W 2
# RES_D 4
# RES_Q 8
# RES_DQ 16
# RES_Y 32
# RES_Z 64
#
# RES_U defines a union. It's arguments are a name and two or more
# pairs of "size, alignment"
#
# The two assigns are only needed if this structure is being nested
# within another. Even if the assigns are not done, one can still use
# STRUCT_NAME_size as the size of the structure.
#
# Note that for nesting, you still need to assign to STRUCT_NAME_size.
#
# The differences between this and using "struc" directly are that each
# type is implicitly aligned to its natural length (although this can be
# over-ridden with an explicit third parameter), and that the structure
# is padded at the end to its overall alignment.

# Alternate "struc-like" syntax:
# STRUCT job_aes2
# RES_Q .plaintext, 1
# RES_Q .ciphertext, 1
# RES_DQ .IV, 1
# RES_B .nested, _JOB_AES_SIZE, _JOB_AES_ALIGN
# RES_U .union, size1, align1, \
# size2, align2, \
# ...
# ENDSTRUCT
# # Following only needed if nesting
# %assign job_aes2_size _FIELD_OFFSET
# %assign job_aes2_align _STRUCT_ALIGN
#
# RES_* macros take a name, a count and an optional alignment.
# The count in in terms of the base size of the macro, and the
# default alignment is the base size.
# The macros are:
# Macro Base size
# RES_B 1
# RES_W 2
# RES_D 4
# RES_Q 8
# RES_DQ 16
# RES_Y 32
# RES_Z 64
#
# RES_U defines a union. It's arguments are a name and two or more
# pairs of "size, alignment"
#
# The two assigns are only needed if this structure is being nested
# within another. Even if the assigns are not done, one can still use
# STRUCT_NAME_size as the size of the structure.
#
# Note that for nesting, you still need to assign to STRUCT_NAME_size.
#
# The differences between this and using "struc" directly are that each
# type is implicitly aligned to its natural length (although this can be
# over-ridden with an explicit third parameter), and that the structure
# is padded at the end to its overall alignment.
