[PATCH v2 3/6] staging: sm750fb: Make internal functions static

[Lorenzo Stoakes <lstoakes@gmail.com>]

This patch declares externally unavailable functions static. This fixes
the following sparse warnings:-

drivers/staging/sm750fb/ddk750_swi2c.c:223:6: warning: symbol 'swI2CStart' was not declared. Should it be static?
drivers/staging/sm750fb/ddk750_swi2c.c:234:6: warning: symbol 'swI2CStop' was not declared. Should it be static?
drivers/staging/sm750fb/ddk750_swi2c.c:252:6: warning: symbol 'swI2CWriteByte' was not declared. Should it be static?
drivers/staging/sm750fb/ddk750_swi2c.c:320:15: warning: symbol 'swI2CReadByte' was not declared. Should it be static?
drivers/staging/sm750fb/ddk750_swi2c.c:361:6: warning: symbol 'swI2CInit_SM750LE' was not declared. Should it be static?
drivers/staging/sm750fb/ddk750_hwi2c.c:63:6: warning: symbol 'hwI2CWaitTXDone' was not declared. Should it be static?
drivers/staging/sm750fb/ddk750_hwi2c.c:93:14: warning: symbol 'hwI2CWriteData' was not declared. Should it be static?
drivers/staging/sm750fb/ddk750_hwi2c.c:160:14: warning: symbol 'hwI2CReadData' was not declared. Should it be static?
