target/dsp563xx: fix scan-build warning

Scan-build triggers a warning:
	Unix API: Allocator sizeof operand mismatch
	dsp563xx.c:2143 Result of 'calloc' is converted to a pointer
		of type 'uint8_t', which is incompatible with sizeof
		 operand type 'uint32_t'

It's a false positive because calloc() is properly used in this
case, as the uint8_t array is used in blocks of 4 elements to read
or write uint32_t values.

Either
	calloc(sizeof(uint32_t), count);
and
	malloc(count * sizeof(uint32_t));
keep triggering the same warning.

Drop the warning by using the constant '4' as size of uint32_t, as
already used few lines below.
