Subject: [PATCH 1/2] ARM: msm: trout: fix 'pointer from integer' warnings

Fix several errors, all in the following form:

arch/arm/mach-msm/board-trout-gpio.c: In function 'trout_gpio_irq_ack':
arch/arm/mach-msm/board-trout-gpio.c:120:2: warning: passing argument 2 of '__raw_writeb' makes pointer from integer without a cast [enabled by default]
  writeb(mask, TROUT_CPLD_BASE + reg);
  ^
In file included from include/linux/io.h:22:0,
                 from arch/arm/mach-msm/board-trout-gpio.c:16:
arch/arm/include/asm/io.h:81:20: note: expected 'volatile void *' but argument is of type 'unsigned int'
 static inline void __raw_writeb(u8 val, volatile void __iomem *addr)
                    ^
arch/arm/mach-msm/board-trout-gpio.c: In function 'trout_gpio_irq_mask':
arch/arm/mach-msm/board-trout-gpio.c:135:2: warning: passing argument 2 of '__raw_writeb' makes pointer from integer without a cast [enabled by default]
  writeb(reg_val, TROUT_CPLD_BASE + reg);
