staging: remove unneeded parentheses around the right hand side of an assignment

In assignments such as value = (FLASH_CMD_STATUS_REG_READ << 24);, parentheses
are not needed. The Coccinelle semantic patch was used to find cases.

@r@
identifier x;
expression e1, e2;
@@

- x = (e1 << e2);
+ x = e1 << e2;
