Use shift for MAX_SIZE

[johnramsden]

Perhaps it makes sense to use a shift so that it's clear that it's a power of two, and to increase it we just increase the shift by one.

Or maybe this should be a compile time variable?

PIM-Embedding-Lookup/upmem/src/dpu/emb_dpu_lookup.c

Line 7 in 1830cfb

#define MAX_SIZE 128 //Must be a power of 2

Potential fix

#define MAX_SIZE (1 << 7) // 128 - Must be a power of 2

Isn't MEGABYTE(14) or MEGABYTE(1) and etc more readable? because in real case problems this MAX_SIZE is gonna be large.

Yeah, good option if it's going to be that large.
