description:
add new cryptographic accelerator driver 'mvxpsec.'

this driver controls CESA unit as same as mvcesa, but uses DMA engines and
does CBC operations, HMAC operations by hardware. about 2 kbytes of data
are processed at one. supported algorithms are:

 - DES-CBC, 3DES-CBC, AES-CBC
 - HMAC-SHA1, HMAC-MD5

non-CBC algorithm such as AES-GCM is not supported by CESA's acceleration
engine. mvcesa is still useful to implement such algorithms as combination of
accelerated block cipher and software chaining.
