[bsp][cvitek] fix c906_little build warning in cache.c

build warning: passing argument 1 of 'inv_icache_range' makes integer
from pointer without a cast [-Wint-conversion]

Analyze: The passed parameter type is void*, which is a pointer type,
but the required type is uintptr_t, which is an integer type. Therefore,
there will be a 'makes integer from pointer without a cast' warning.

Solution: casting the void* pointer to uintptr_t, ensure that the
function receives the correct type.
