Convert REG_PATTERN_TEST and REG_SET_AND_CHECK macros to functions
Reduces x86 defconfig image by about 3k

compiled, untested (no hardware)

Signed-off-by: Joe Perches <joe@...ches.com>

New:

$ size vmlinux
   text    data     bss     dec     hex filename
4792735  490626  606208 5889569  59de21 vmlinux

Current:

$ size vmlinux
   text    data     bss     dec     hex filename
4795759  490626  606208 5892593  59e9f1 vmlinux

Changed since last submission:

Fixed existing controler->controller typo
Added E1000_REG_ADDR macro
Added E1000_FLASH_ADDR macro
The #define E1000_PHY_CTRL conflicted with the PHY_CTRL
expansion when using the E1000_REG_ADDR macro and was
renamed to E1000_PHY_CTRL_CSR
