[PATCH 1/3] crypto: marvell/octeontx: Simplify bitmap declaration

[Christophe JAILLET]

'OTX_CPT_ENGS_BITMASK_LEN' is only used to allocate a bitmap. This macro
only works because OTX_CPT_MAX_ENGINES is 64. BITS_TO_LONGS() should be
used to compute the correct size.

In order to simplify the code, remove OTX_CPT_ENGS_BITMASK_LEN and use
DECLARE_BITMAP to declare the 'bits' bitmap.
