Yes.

This is wrong. kbuild has knowledge how to copy a file named:
apicnt.o_shippd to apicnt.o
So you renamed the supplied .o fiel to apicnt.o_shipped and delte your
own rule.

Please do:
phone_mrvl-$(CONFIG_PHONE_LEGERITY) := mrvphone.o slic.o legerity.o
phone_mrvl-$(CONFIG_PHONE_LEGERITY) += vp_hal.o sys_service.o apicnt.o
phone_mrvl-$(CONFIG_PHONE_LEGERITY) += apiinit.o apiquery.o vp_api.o
phone_mrvl-$(CONFIG_PHONE_LEGERITY) += vp_api_common.o mvutils.o

Here you could do:
extra-cflags-$(CONFIG_PHONE_LEGERITY) += -D__LEGERITY__
extra-cflags-$(CONFIG_PHONE_PROSLIC) += -D__PROSLIC__
EXTRA_CFLAGS += $(extra-cflags-y)
Please delete the rest - it is not needed.

When you build your module use:
make -C $PATH_TO_COMPILED_KERNEL M=`pwd`
See also Documentation/kbuild/modules.txt for further reference.
