[PATCH v4 4/7] drivers/dma: eliminate dependency on non-portable __SIZEOF_LONG__

[Andre Muezerie <andremue@linux.microsoft.com>]

Macro __SIZEOF_LONG__ is not standardized and MSVC does not define it.
Therefore the errors below are seen with MSVC:

../lib/mldev/mldev_utils_scalar.c(465): error C2065:
    '__SIZEOF_LONG__': undeclared identifier
../lib/mldev/mldev_utils_scalar.c(478): error C2051:
    case expression not constant

../lib/mldev/mldev_utils_scalar_bfloat16.c(33): error C2065:
    '__SIZEOF_LONG__': undeclared identifier
../lib/mldev/mldev_utils_scalar_bfloat16.c(49): error C2051:
    case expression not constant

Turns out that the places where __SIZEOF_LONG__ is currently
being used can equally well use sizeof(long) instead.
