Recently there wre some changes in McBSP driver for multi-omap support. Earlier 
read/write calls used to be
defined as a macro and now it has been converted to a function, hence the 
compilation error (implicit declaration of
function 'OMAP_MCBSP_WRITE') .  you can look for recent patches for
arch/arm/plat-omap/mcbsp.c file.

i have a question, why a client is modifying mcbsp registers. There is a mcbsp 
config function (omap_mcbsp_config) exported which you can use to
configure mcbsp registers.
if its an absolute necessity you can use omap_mcbsp_read and omap_mcbsp_write 
function. which are defined in arch/arm/plat-omap/mcbsp.c.
but you need to pass full register name, like OMAP_MCBSP_REG_SPCR1 instead of 
just SPCR1 ( 'SPCR1' undeclared  error).
