FMD: Reset FManV3L DEFAULT_totalFifoSize to default 156K

In T1040RMDPAAAP_Rev.C, at page 103, Figure A-38 says that the Reset
value of FMan_V3L of BMI Configuration 1 Register (FMBM_CFG1) is
0x026F0000, which implies that FBPS should be 0x26F = 623.  So the
size of free buffer pool is 624 * 256bytes = 156KB, and 156K =
5*0x6400 + 0xa00 + 2*0x3200 = 5*1G + 1*OH + 2*OP.  So it is OK to
most cases while keep the default reset value for FMBM_CFG1.
Without this vaule, sometimes DPA Eth driver (offline port) and FMD
driver might report errors like below while more than 1 offline ports
are added in t1040rdb/qds dts.

dpa-fman0-oh@2 {
	compatible = "fsl,dpa-oh";
	/* Define frame queues for the OH port*/
	/* <OH Rx error, OH Rx default> */
	fsl,qman-frame-queues-oh = <0x68 1 0x69 1>;
	fsl,bman-buffer-pools = <&bp6>;
	fsl,qman-frame-queues-tx = <0x90 8>;
	fsl,fman-oh-port = <&fman0_oh2>;
};
dpa-fman0-oh@3 {
	compatible = "fsl,dpa-oh";
	fsl,bman-buffer-pools = <&bp6>;
	/* Define frame queues for the OH port*/
	/* <OH Rx error, OH Rx default> */
	fsl,qman-frame-queues-oh = <0x52 1 0x53 1>;
	fsl,fman-oh-port = <&fman0_oh3>;
};
/* The following OP is used as inbound OP*/
dpa-fman0-oh@4 {
	compatible = "fsl,dpa-oh";
	fsl,bman-buffer-pools = <&bp6>;
	/* Define frame queues for the OH port*/
	/* <OH Rx error, OH Rx default> */
	fsl,qman-frame-queues-oh = <0x54 1 0x55 1>;
	fsl,fman-oh-port = <&fman0_oh4>;
};
