accel/ivpu: ivpu_ipc needs GENERIC_ALLOCATOR

Drivers that use the gen_pool*() family of functions should
select GENERIC_ALLOCATOR to prevent build errors like these:

ld: drivers/accel/ivpu/ivpu_ipc.o: in function `gen_pool_free':
include/linux/genalloc.h:172: undefined reference to `gen_pool_free_owner'
ld: drivers/accel/ivpu/ivpu_ipc.o: in function `gen_pool_alloc_algo':
include/linux/genalloc.h:138: undefined reference to `gen_pool_alloc_algo_owner'
ld: drivers/accel/ivpu/ivpu_ipc.o: in function `gen_pool_free':
include/linux/genalloc.h:172: undefined reference to `gen_pool_free_owner'
ld: drivers/accel/ivpu/ivpu_ipc.o: in function `ivpu_ipc_init':
drivers/accel/ivpu/ivpu_ipc.c:441: undefined reference to `devm_gen_pool_create'
ld: drivers/accel/ivpu/ivpu_ipc.o: in function `gen_pool_add_virt':
include/linux/genalloc.h:104: undefined reference to `gen_pool_add_owner'
